Kinetic theory and temperature in gases

  • #1

Homework Statement


Temperature of a gas (in kelvin) is proportional to the average kinetic temperature of its particles.

Question: The temperature of 55k (277C) to 1100k(827C). At 277C the mean kinetic energy of the gas is 1.14x10^20. What is it at 827C?


Homework Equations


kinetic energy= ½ x mass x (velocity)²


The Attempt at a Solution



55k to 1100k is x20. 1.14x10^20 x20=2.28x10^21.

Just wanna check this is correct as I have an exam tormorrow.

I'm fairly out of it because I'm pretty tired, but seems alright to me.
