Hello colleagues, I have a seminar that i need to turn in a weeks day from now. My professor listed the following questions, guidelines that I should lean on: 1) Is it possible to achieve a temperature bellow absolute zero (-273,15) 2) An ideal gas contracts linearly when decreasing temperature towards absolute zero, why? 3)A real gas doesnt contract linearly,why? it has more variables than the ideal gas, but this is not the complete answer. 4)Why is the absolute zero temperature the common ending point for both(real and ideal) colleagues, i think the answer here lies in the specter that lies deeper than what most engineers abide by. We must go deeper than continuum, i think all the answers can be interpreted through the molecular level. And now im asking you if you know any good links that could help me with my seminar. Also if you have any helpful information feel free to share.
