Room temperature if a refrigerator is kept open?

The room temperature will increase.  I could make a complicated thermodynamics argument, but the simple way to think of it is this: since the refrigerator is plugged in, energy is continuously entering the room.  Since the room is "thermodynamically closed," no energy is leaving the room, so the net energy of the room must be increasing (i.e. the temp is rising).

If the room has no losses then the formula would look like this:\n\nIncrease in degree C = constant times h n t / V \nwhere \nh = the heat produced by 1 person (say 30 Watt)\nn = number of persons in room\nt = time \nV = volume of room\nIf we take the volume in liters and the time in seconds the constant is 0.77. \n\nOne person, one hour in a completely isolated typical room of 18000 liters (no losses) would increase the temperature by 4.5 degrees Centigrade.  In reality the heat is lossed via the walls and windows.

Room temperature, in laboratory reports, is taken to be roughly 21–23 degrees Celsius (69-73 degrees Fahrenheit), or 294–296 kelvin.\n\nIn describing an experiment, when researchers specify its temperature no more precisely than as "room temperature," this implies they have assumed that temperature differences of a few degrees do not matter to the phenomenon or question they were investigating. Typically researchers do not closely watch or control the temperature of a "room temperature" experiment.\n\nThe phenomena that researchers may chose to study at room temperature can naturally occur in the range of 21–23 °C, or they may not. Researchers will choose to study a process outside its natural temperature range when they expect the conclusions to a specific question to be the same at room temperature as at a more natural temperature.\n\nExperimentalists have an advantage in anticipating aspects of a room-temperature experiment, because the temperature is close to 25 °C (77 °F, 298 K), at which many of the material properties and physical constants in standards tables have been measured (more at standard state). By consulting such tables, a researcher may anticipate, for example, how fast a chemical reaction is likely to proceed.\n\nUltimately, a scientist conducts experiments at room temperature because it is convenient. The convenience may be only modest, as in cases where researchers might have performed a more realistic experiment simply by placing some material in an oven or refrigerator. Or it may be more like a necessity, as in cases where maintaining a firm control over the temperature of apparatus and the other elements involved would pose significant conceptual, technological or financial challenges.\n\nWhen researchers have chosen either not to measure or not to control the temperature of an experiment; when they perform their experiment outdoors, or in a room where they perceive that the temperature varies either in time or in the space around an experiment; or when they simply sense that the temperature is beyond the range of 21-23 °C, they are liable to report that they conducted it at ambient temperature. Whether they do so may depend on whether they believe the process or question they are investigating could be sensitive to the size of the deviations from room temperature they expect.\n\nBeing a less precise specification than even "room temperature", "ambient temperature" is more certain to be accurate. Because scientists strive for accuracy in their reports, many use this specification exclusively just as a matter of course, even to describe experiments that they could justifiably characterize as having been conducted at room temperature.\n\nArguably, no precision is lost in this practice: In disciplines where experimenters always work in laboratories, and where temperature differences of a few degrees make little difference with regard to the questions that scientists ask, the distinction between ambient and room temperature literally is not worth making. And, of course, the ambient temperature of a room is room temperature.\n\nYet small temperature differences have large effects on many natural processes. Therefore scientists who do observe a distinction between the two specifications may be sticklers about which one to apply. For example, heat given off by electronics or motors may warm the area around an experiment relative to the rest of a room. Under such circumstances, and depending on the question under investigation, some scientists would consider it inaccurate to report that an experiment took place at room temperature.

law of conservation of energy\nany gas that is compressed will 'lose' its heat energy to the ambient temperature in the process (ie a refrigerator). in the specific example the gas (1 cm3 at 70F )is at room temperature until its expanded to lets say 1000 cm3, now 70F is spread out 1000x the area,(as is the gas in the can) the more the 70F is expanded the 'colder' it gets (much like the universe or a car tire, but its all relative)

close the light in the house....then go to the kitchen and open the door of the fridge.....this is where the light goes...haahahahhahahahahahahahahaha

I dont understand your question.  How can things work without electricity?  Electricity is power.  And power is essential for any instrument to work.  Do you mean to ask about using alternative electricity?\n\nYeah you can put the fridge in snowpacked mountains which will make things inside cool.

Running a small refrigerator using an electric generator is not very economical but can be done during a blackout.  It may be necessary to run the generator only periodically especially if you open and close the door oonly just before running the generator and check if the refrigerator is actually operating (listen for vibrations?) while you are running the generator.  If the refrigerator is small enough (dormitory type?) you may be able to use a DC/AC converter that plugs into an automobile cigarette lighter and a long extension cord.  Read the amps/watts/volts/hertz(60 cycle?) from the manufacturer's label and show that to the generator supplyer.  In a recent blackout, we used such a converter to run fans in a basement fireplace insert that heated the house burning firewood while tempertures dipped well below freezing outside (save the pipes!!!).  Good luck.

Not as much as they used to. Refrigerators work by using a liquid in a closed system. The liquid expands by taking heat from the inside and rising. By rising, a fluid current is created that keeps things running along. At the bottom of the system, a fan blows to cool the fluid back down and keeps the circulation going. If you lay it on a side, the circulation stops, and bubbles may form, which will make it difficult to start it up again. These systems are a lot tighter than they used to be and bubbles are not as likely to form.

a refrigirator works by separating cold and heat, it's call a heat pump and can be used for both heating and cooling of small or large containers. It takes the cold and holds it inside and keeps the heat away. If you open the door of the refrigerator it equalizes the heat. The room temp will not go up or down but you will expend energy and burn your motor out.

A refrigerator (often called a "fridge" for short) is an appliance for the storage and preservation of perishable food; food kept in a refrigerator lasts longer than that left at room temperature as the cold inhibits bacterial growth. A refrigerator maintains a cold temperature above the freezing point of water; commonly refrigerators are used in conjunction with freezers, which maintain temperatures below freezing, or a refrigerator may have an integrated freezer compartment. The refrigerator is a relatively modern invention amongst kitchen appliances. It replaced the common icebox which had been a household item for almost a century and a half prior, and is sometimes still called by the name "icebox".\n\nCommercial units, which go by many other names, were in use for almost 40 years prior to the common home models. The fact that they operated with toxic ammonia gas systems made them unsafe for home use. Practical household refrigerators were introduced in the 1920s and gained wider acceptance in the 1930s as prices fell and non-toxic, nonflammable synthetic refrigerants, such as Freon or R-12 refrigerants were introduced.\n\nthe advantages and disadvantages u can look straight to my source... it has many information... i hope this helps... good luck ^^

it has more to do with the differant tempatures\nto put a light in the freezer you need to shield it from the frozen tempatures\n\nin the fridge this is nota prob since tempatures are above 32 deg fahrenhiet

In a dark cool area, I store mine in the closet which is in the inner most corner of my house, it's pretty cool in there.\nJust keep it out of extreme temperature swings and light.

"Keep the temperature of hot food above 140°F / 60°C and keep the temperature of cold food below 40°F / 4°C. Food should not sit at intermediary temperatures (defined as 40-140°F / 4-60°C) for more than 2 hours."

Good point! \nCongratulations, that's got me thinking. Ouch!\n\nCould it have something to do with maintaining the frozen goods in the freezer, which obviously is less important in a fridge. Afterall, when the light comes on in the fridge it produces kinetic energy that turns the light into heat which could linger trapped inside once the door is shut again. \n\nWell, that's my feeble attempt at an answer. It would just drive me crazy otherwise!

You need tempertures above 1764 °F.  It is best done in a ceramic container.
