Asample of an ideal gas is in a tank of constant volume. the sample absorbs heat energy so that its temperature changes from 328 k to 1312 k. if v1 is the average speed of the gas molecules before the absorption of heat and v2 their average speed after the absorption of heat, what is the ratio v2/v1?

Explanation:

= Boltzmann constant =

T = Temperature

m = Mass of the molecules

The RMS velocity of molecules in a gas is given by

It can be seen that RMS velocty is proportional to temperature

The ratio of the velocities is

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
