Kinetic Theory - Result Question 35

35. If for a gas, RCv=0.67, the gas is made up of molecules which are

[1992]

(a) diatomic

(b) mixture of diatomic and polyatomic molecules (c) monoatomic

(d) polyatomic

Show Answer

Answer:

Correct Answer: 35. (c)

Solution:

  1. (c) Since RCV=0.67CV=32R, hence gas is monoatomic. For a gas having f degree of freedom specific heat at constant volume, Cv=12fR specific heat at constant pressure,

Cp=(f2+1)R

where, R= universal gas constant
