Q. The root mean square value of the speed of the molecules in a fixed mass of an ideal gas is increased by increasing

Kinetic Theory

Solution:

The root mean square velocity of a gas is given by:
$V _{ RMS }=\sqrt{\frac{3 RT }{ M }}$
As we can see, increasing the temperature alone can increase the RMS velocity of sample of gas irrespective of pressure or volume changes.
