NEET Physics Kinetic Theory of Gases Questions Solved

NEET - 2015

The ratio of the specific heats CP/CV=γ in terms of degrees of freedom (n) is given by

(a)(1+1/n)

(b)(1+n/3)

(c)(1+2/n)

(d)(1+n/2)

The specific heat of gas at constant volume in terms of degree of freedom n is

CV=n2R

Also CP-CV=R

So, CP=n2R+R=R(1+n2)

Now, γ=CP/CV=R(1+n2)/n/2R=2n+1
