Two statements are given below.
Statement-I: The ratio of the molar volume of a gas to that of an ideal gas at constant temperature and pressure is called the compressibility factor.
Statement-II: The RMS velocity of a gas is directly proportional to square root of $\mathrm{T}(\mathrm{K})$
The correct answer is
Both statement-I and statement-II are correct
Both statement-I and statement-II are not correct
Statement-I is correct but statement-II not correct
Statement-I is not correct but statement-II is correct
Solution
Both statement I and II are correct.
$v_{\mathrm{rms}}=\frac{\sqrt{3 \mathrm{kbT}}}{\mathrm{m}}$ For this equation $v_{\mathrm{rms}} \propto \sqrt{\mathrm{T}}$
