Q138 / 160 · TS EAMCET 2025 (04 May Shift 1) · Physics

If the temperature of a gas is increased from $127^{\circ} \mathrm{C}$ to $527^{\circ} \mathrm{C}$, then the rms speed of the gas molecules

A
increases by 4 times
Correct answer
B
becomes $\sqrt{2}$ times
C
becomes half
D
decreases by $\sqrt{2}$ times

Hence, the correct answer is option: 'B'.
