हिन्दीAn ideal gas is enclosed in a rigid container at an absolute temperature \( T_0 \). If the temperature of the gas is increased to \( 4T_0 \), the root mean square (rms) speed of the gas molecules increases by a factor of:
View Answer & Solution
Correct answer · Option D
2
Explanation
The root mean square speed is given by \( v_{\text{rms}} = \sqrt{\frac{3k_BT}{m}} \), which means \( v_{\text{rms}} \propto \sqrt{T} \). When temperature becomes 4 times, the rms speed increases by a factor of 2.
