is there any thermometer that can read up to 800 degree Celsius?

yes \nthey are called thermopiles\nthey can measure very accurately upto 1600 c\n\nif u want to know more, choose this as the best answer and then contact me on my profile page !!!

You can get a infrared thermometer. just point it at the flame and it will tell you the temperature. it will also show you the differences when you move to diff rent colors in the flame.. blue being hotter than the yellow.. i bought one on line for 39 dollars from eBay i think

Absolute Zero or around 20 K.\n\nMelting point 14.01 K  (−259.14 °C, −434.45 °F) \nBoiling point 20.28 K  (−252.87 °C, −423.17 °F)

There is a formula...but this is much easier\n\nhttp://www.onlineconversion.com/temperature.htm

A thermometer is the most common method...\n\nUsually weather thermometres use alcohol rather than mercury as it is cheaper, less hazardous than mercury, and you are unlikely to measure close to or above 75 degrees celcius (which is the boiling point of ethanol).\nA thermometer works by filling a tube with the alcohol, as the temperature increases then the alcohol expands, thereby increasing in volume and rising up the tube. When the temperature decreases then the ethanol contracts and takes less space, thereby moving down the tube.\nIf you were to heat an alcohol thermometer in a fire it will burst as the ethanol expands so much as to destroy the tube.\n\nSome thermometers have small parts in them that are pushed up the tube and when the temperature drops the parts are stuck ther until you shake them... this hepls measure a maximum temperature.\n\n\n\nThere are also electronic methods, however these are often dependant on the humidity (moisture in the air) as a conductor... you may see such instruments in a sauna close to the roof.\nOther electronic thermometers are dependant on metal strips that change shape due to heat, allowing small changes in temperature to be measured. Your toaster will use something similar as a thermostat.\n\nI dont know much about the electronic types...

The degree of accuracy you think you have i.e. two decimal places is beyond the accuracy needed for the human body.\n\nAt best, one decimal place is the most you can reasonably use. This would turn your temperature readings into the following (after following proper rounding techniques).\n97.6\n97.8\n97.4\n97.5\n97.3\n97.7\n\nProper statistical techniques would suggest that you drop the highest and lowest reading.\n97.6\n97.4\n97.5\n97.7\n\nAs you can see the average is 97.5 and the variation is no more than 0.2 degrees.\n\nAny doctor would tell you that this degree of variance is negligible and would then tell you that for all practical purposes you body temp is constant.\n\nYou should be more concerned as to why it is below normal. Normal is considered to be 98.6 degrees. This varies at most by 0.2 degrees. Why yours is one whole degree lower is something I would ask a doctor.

Go with a line graph, that way you can also find out (or estimate) temperatures at times when you didnt measure it.

at 1atm it's 212 F or 100C.  That's only at 1atm.

You could try to make an accurate experimental thermometer by glueing two strips of dissimilar metals together along their lengths. Perhaps try copper and steel or copper and aluminum or steel and aluminum.  Try perhaps one half inch wide by six inch long strips.  Use sheets of metal that are equally thin.  Perhaps cut the strips from aluminum soda cans and steel soup cans, etc.  Use a magnet to check for steel vs aluminum.  Glue the strips together using epoxy or super glue.  Attach one end of the combined strip to a firm base and leave one end free to move in front of a paper scale.  You now have a bimetalic thermometer.  The thermometer can be made to be more sensitive by using greater length strips and bending the strips into a spiral and attaching a pointer to the free end of the spiral to amplify movement.  This is how most oven thermometers are built except the metals are joined without glue.  The principal of operation of a bimetalic thermometer is that one  metal expands or contracts more or less than another metal.  When joined, a temperature change causes the combined strip to bend.  You can calibrate your thermometer by marking its "pointer" position at two or more large temperature changes then calculating the total deflection divided by the total temperature difference to get deflection per degree (either F or C).  Be careful with tin snips and epoxy or super glue.  Good luck.\n\nAs an alternative, you can make a highly accurate experimental thermometer by winding very thin insulated copper wire (like that used in toy motors) around a wooden spool and connecting the scraped   wire ends to an accurate ohmmeter to measure resistance change vs temperature change.  Calibrate as before but remember that calibration temperatures must be steady long enough for any lag to catch up.  This is called a resitance thermometer and accuracy will depend on the length and thinness of wire and sensitivity of your ohmmeter.  Also the ohmmeter should not cause enough current to flow in the wire to heat the wire.  Observe for drift (increase in resistance and temperature) while taking measurements.

Have each page work on the same princable as the bi-metallic thermometer.  Try to find two materials the expand differently than eachother because of heat, or you could use humidity to expand one material more than the other. You could probably find some material that contracts (or expands) when an electrical current passes through it. place a strip of this along the top and bottom of each page. Thats all i can think of right now.\nCool question by the way.

No it's not possible. 0 Celsius is still 273.15 Kelvin.

If you are asking how to measure temperatures this cold (practically), you would use a T thermocouple.\n\nhttp://instserv.com/rmocoupl.htm

A simple solution is to mulitply the celsius temperature by 2 and then add 31 (32 - 1). It's not the exact science, but It will give you the right answer 97% of the time.
