Show that for an ideal gas `C_p - C_v = R` where `C_p` and `C_v` are the heat capacity at constant pressure and constant volume respectively.

Show that C_P- C_V = R

Establish the relation C_p-C_v=R

The ratio of specific heat of a agas at constatnt pressure to that constatnt volume is gamma . The change in internal energy of one mole of a gas when volume changes from V to 2V at constant pressure P is

Answer the following questions based on the P-T phase diagram of CO_2 : Describe qualitatively the changes in a given mass of solid CO2 at 10 atm pressure and temperature 65^-@C as it is heated up to room temperature at constant pressure

In van der Waals' equation (P + (a)(V^2) (V - b) = RT, what are the dimesions of a and b? Here, P is pressure, V is volume, T is temperature and R is gas constant.

Show that in a equipotential surface, v is constant if r constant (v = potential and r = distance).

A gas occupies 22.4 L in NTP. Calculate the volume occupied it at 30^@C and 665 mm pressure.

For a certain mas of the gas at constant temperature draw a graph between the volume against the corresponding pressure i.e. V vs P.
