Question
If the absolute temperature of a gas is quadrupled, how many times will the root mean square velocity of its molecules increases? How many times will its total energy increase?
✓

Answer

$\therefore{ } C _{ rms } \propto \sqrt{ T }$
Therefore, by increasing T, 4 times, it will double and $E \propto T$ i.e. energy will become four times.
