Which of the assumption of the kinetic molecular theory best explains the observation that a balloon collapses when exposed to liquid nitrogen (which is much colder than a cold winter day)?
View answer and explanation
Correct option: B
The velocity of gas molecules is proportional to their kelvin temperature
Option B is correct because the kinetic molecular theory states that the velocity of gas molecules is proportional to their Kelvin temperature, explaining why a balloon collapses when exposed to liquid nitrogen.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
