The correction factor 'a' to be the ideal gas equation corresponds to-

A

forces of attraction between the gas molecules

B

density of the gas molecules

C

electric field present between the gas molecules

D

volume of the gas molecules.

Text Solution

Verified by Experts

The correct Answer is:
A
In the real gas eqaution, `(P+(an^(2))/(V^(2)))(V-nb)=nRT`,
van der waals constant 'a' represents the intermolecular forces of attraction between the molecules.

    the change in internal energy of the gas and the work done by the gas are equal in magnitude in an adiabatic process
    C
    the internal energy does not change in an isothermal process
    D
    no heat is added or removed in an adiabatic process
