Select the odd man out from the following statements.

A

Pressure of a gas P `=1/3 nmv^2`

B

Average kinetic energy per molecule is K.e =`3/2 KT`

C

For a cyclic process the net heat transferred to the system is equal to the work done by the gas `Q_("net")=Q_("in")-Q_("out")=W`

D

In terms fo kinetic energy pressure of a molecule of a gas
= `2/3xx` kinetic energy per molecule.

Text Solution

Verified by Experts

The correct Answer is:
C

Statement c is related thermodynamics whereas other statements (a),(b) and (d) are related to kinetic theory of gases.
