when the temperature of matter increases the particles

Surprisingly, the increase of temperature is accompanied by the continuous loss of total gas energy. Here, we report that for a granular gas of aggregating particles, the granular temperature does not necessarily decay but may even increase. For a homogeneous granular gas of identical particles, the corresponding decay of granular temperature is quantified by Haff’s law. I will skip the details (you can do it at home for fun), but I get the following equation.The kinetic energy of a force-free granular gas decays monotonously due to inelastic collisions of the particles. Now I can use these points to find the slope of the line and the point-slope formula to find the equation of the line. This gives two x-y points (except x is Fahrenheit temperature and y is the Celsius temperature) that are (32,0) and (212,100). Good thing I already have them-they are the boiling and melting point of water. To do this, I need two data points to make a line. How do you convert from ☏ to ☌? Since both of these are linear temperature scales, I can find a function for the Celsius temperature as a function of Fahrenheit temperature. Anyway, when the MythBusters tested the thermal properties of a tauntaun they used a temperature of -40-so there. So, I'm going to guess that maybe during the day it is -40☌ (or ☏). OK, if you look at Wookiepedia (the Star Wars Wikia) it says that Hoth gets down to -60☌ at night. But the correct answer to the significance of -40° is that it is the temperature on Hoth. If you convert -40☏ to Celsius, you get -40☌. Oh well, I guess we won't know until someone invents a time machine. This wouldn't quite work fitting in the human body temperature at 100 ☏, but it would be close. One idea is that the scale is broken into three parts, each of 32 °s, since 32 is the temperature of freezing water. Still, there does not seem to be complete agreement as to why the human body temperature measures at 98 ☏ instead of 100 ☏. That is surprisingly cold and why you use salt-ice mixture to make homemade ice cream. If you mix ice and salt (and a little water), the coldest you can get the mixture is zero. Actually, this is something that's interesting.

With the Kelvin scale, you don't get negative temperatures-so that's useful in lots of calculations.īut what about the Fahrenheit scale? I think that everyone will agree that it is based on two measurements: the temperature of a human body (around 98 degrees Fahrenheit) and the temperature of salt and ice (0 ☏). The Kelvin scale is just like the Celsius scale, but it is shifted by 273.15 such that 0 Kelvin (there are no degrees on the Kelvin scale) is equal to 273.15 degrees Celsius. That's fairly easy to reproduce but these values do depend on atmospheric conditions, so it's not a perfect method to calibrate a thermometer. The zero value is at the freezing point of water and the 100 value is at the boiling point. How do you calibrate a temperature scale? The Celsius scale is easy.

Instead, you can just check out this very awesome post by Aatish Bhatia in which he explains entropy using sheep. First, what is entropy? I could try to explain entropy, but this would be a complete new blog post. Temperature is the rate that internal energy changes with respect to entropy. This one is pretty tough, so hold on to something. Now for the second definition of temperature. Really, you could say that the thermometer even came before the idea of temperature. Since both mercury and alcohol expand with an increase in temperature, you can determine the temperature based on this thermal expansion (or contraction). When you put this thermometer in a liquid or something else, the temperature of the liquid inside the thermometer changes until it is the same as the object. Take your basic mercury or alcohol thermometer (the mercury ones are not so common because-you know, they contain mercury).

But really, this temperature is the basis of most thermometers.
