Question

Statement - 1 : RMS velocity of a gas sample can be expressed as $C_{rms}=\sqrt{\frac{3PV}{M}}$
and
Statement - 2 : The RMS velocity of a gas sample decreases if its volume is decreased.

• A. Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1
• B. Statement-1 is true, Statement-2 is true; Statement-2 is NOT a correct explanation for Statement-1
• C. Statement-1 is True, Statement-2 is False
• D. Statement-1 is False, Statement-2 is True

Answer 1

The correct option is C Statement-1 is True, Statement-2 is False

At constant temperature, PV is constant, PV remains same whether the volume increases or decreases. So statement -2 is wrong.
