A spherical balloon is filled with an ideal mono-atomic gas. At some instant its pressure was , volume and temperature . If the balloon expanded in such a manner so that the rate of radiation from the balloon remained constant. It was found that the work done by gas inside the balloon was when its volume increased to 8.Find the value of n. (Assume ambient temperature to be close to 0 K)
Rate of radiation = = constant
or = constant
or = constant
or
or = constant (1)
Comparing it with polytropic equation = constant
We get
Work done by gas =
=
So n = 2
