What is hotter, boiling water or boiling oil?
89995
There's many kind of oil with different boiling point. But generally, as oil's boiling point is higher than water (boiling point of oil of turpentine is 159ºC and water is 100ºC), boling oil is hotter than boiling water.

At a higher elevation the pressure on the water is less therefore it will boil at a lower temperature than it would at sea level.\n\nA liquids state of matter depends on pressure and temperature to make something from liquid to gas you use high temperature and low pressure.

Definitely. After all, water vapor is just the gaseous form of water, and you can heat that quite a bit more. \n\nHowever, I presume you are referring to the liquid form of water. The previous answer is definitely correct. All one has to do is increase the pressure and the liquid water will stop boiling and get hotter.

The cold water froze about 10 or 15 minutes faster than the hot water, and there was no detectable difference between the boiled water and the other kind. Another old wives' tale thus emphatically bites the dust. Science marches on.

Steam isn't "hotter", it's still at 100°.  What it has though is more heat energy in it kg for kg.  The extra energy is the heat of vaporization and it's the reason the steam takes up so much more volume than the water at the same temperature.  The water molecules have the same average kenetic energy - temperature - but they occupy much less space.

The correct answer is B, leave water on the bench at room temp and watch it evaporate. Boiling is the temperature at which the vapour pressure equals the atmospheric pressure.

The lower the air pressure, the lower the boiling point of water.

If you think about a comparison scale, water boils at 100 degC and 212 degF.  If you equate the units and heat water to 100 degC it will boil, but if you heat water to 100 degF, you have a nice bath.\n\nSo, an increase in temp of 1 degC if more than 1 degF.\n\nOr, imperically:\n\ndegF = 1.8(degC) + 32.

ummm, no, water doesn't always boil at 100C.  It boils at 100c at one atmosphere, water will boil at room temperature in a vacuum.  But, hot water will boil faster, it requires less energy to heat the water, and the less water you have to boil the faster it will reach the boiling point.

No.  You would have to heat the cold water up to the temperature that the hot water is at and then go past it to get to the boiling point.  It works in reverse when freezing.  Hot water will not freeze faster than cold, because you have to remove heat just to get to the point the cold water is already at.\n\nThe cool part is you can do this experiment at home.  Put two pans on to boil, one with cold the other with hot, and see which one boils first.  You don't have to take my word for it.

Hot\n\n\nThe Mpemba Effect is a special phenomenon where hot water freezes faster than cold water. The discovery of this effect was made by a high school student named Mpemba in Tanzania, Africa in 1969. He noticed this phenomenon while making ice cream and was curious enough to make note of it. His teachers did not believe it was possible, and it took several years until university professors finally accepted his discovery.\n\n\nWhich Boils Faster??

Consider a liquid (water) and its gas (steam).  To convert water to steam, you first have to heat water to 100 C.  At that point additional energy begins to boil the water.  This is the process where water molecules have enough energy to overcome the attractive force between them (called cohesion, in this case, due to the dipolar attraction between waters).\n\nYou are right in that gases are higher energy (could say hotter), but that's because they've taken the energy from whatever heat source was around when they vaporized.\n\nBack to the water example, water on your skin feels cold because it's absorbing heat from your skin and as the water evaporates, that heat is carried away by the vapor phase molecules (which are moving faster than the liquid form).\n\nThe fast-moving particles from your question have a lot of heat stored, that's why steam at 100 C is more likely to burn your skin than water at 100 C.  It has more heat to transfer.\n\nAs for freon, it depends on which freon you're talking about.  Freon 12 (one of the ones phased out because of ozone depletion) melts at -158 C (Merck Index).

Here's the thing: \nAdding salt to water actually increases the boiling point of water, so depending on how much salt you use, your boiling point of salt water could be something like 105 degrees celsius instead of 100.  Boiling point raising is an example of a colligative property, which is a property that is not dependent on what kind of particles you're using, just how many particles there are.  So if you added more salt, the water's boiling point would be higher.  \n\nThat means that your water would have to be at a higher temperature to boil.  This means that reasonably, it would take longer for you to get your water to that higher temperature, but not by a lot.  It would be roughly the same amount of time.  \n\nThe trick, though, is that because your water is boiling at a higher temperature, whatever you're cooking in that water is going to cook faster.  You're cooking it at 105 degrees instead of 100, so whatever you're cooking in the water will be done faster.  That's probably what your high school chemistry teacher meant.

It will boil faster in the larger pot IF\n1) the larger pot has a larger base\n2) the same amount of water is in both the smaller and larger pot.\n\nThe water will boil faster because more water is in contact with the base of the pot, which has more contact with the heating element.

The one that heats up faster AND to higher temperatures is soil.\n\nWater can not gain or lose heat as quickly as soil due to latent heat. Water absorbs heat until it reaches the next phase change (vaporization) in which the water changes state.

A liquid boils when its vapor pressure equals the pressure above the liquid.  At a given temperature, the vapor pressure of a liquid is constant.  At higher altitudes, the atmospheric pressure (the pressure above the liquid) is less than it is at lower altitudes, so water will boil at a lower temperature.
