Consider a spherical shell of radius R at temperature T. The black body radiation inside it can be considered as an ideal gas of photons with internal energy per unit volume `u=U/V propT^4` and pressure `P=1/3(U/V)`. If the shell now undergoes an adiabatic expansion the relation between T and R is :

A

`Tprope^(-R)`

B

`Tprope^(-3R)`

C

`Tprop1/R`

D

`Tprop1/(R^3)`

At pressure P and absolute temperature T a mass M of an ideal gas fills a closed container of volume V. An additional mass 2M of the same gas is added into the container and the volume is then reduced to V/3 and the temperature to T/3 . The pressure of the gas will now be:

If P,V,M,T and R are pressure, volume, molar mass, temperature and gas constant respectively, then for an ideal gas, the density is given by "________________" .
