what is Cp and Cv

Does a solid also have two kinds of molar heat capacities C_p and C_v ? If yes , do we have C_p gt C_v ? Is C_p - C_v = R ?

If for H_2 gas, C_p -C_v=a and for O_2 gas, C_p-C_v=b ,where C_p and C_v is heat capacity in cal/g-k,then select the correct relation

What do you understand by C_p and C_v ?

The ratio of the molar heat capacities of an ideal gas is (C_p / C_v = 7/6) . Calculate the change in internal energy of 1.0mole of the gas when its temperature is raised by 50 K , (a) keeping the pressure constant , (b) keeping the volume constant and (c ) adiabatically.

Prove that C_p - C_v = R .

C_p and C_v are specific heats at constant pressure and constant volume respectively. It is observed that C_p - C_v = a for hydrogen gas C_p = C_V = b for nitrogen gas The correct relation between a and b is:

The ratio (C_p / C_v) for a gas is 1.29 . What is the degree of freedom of the molecules of this gas?

Dry air at 15^0 C and 10 atm is suddenly released at atmospheric pressure. Find the final temperature of the air [C_p / C_v = 1.41] .

Calculate the ratio (C_p / C_v) of oxygen from the following data . Speed of sound in oxygen (= 32g mol^(-1)) and the gas constant (R = 8.3 J K ^(-1) mol^(-1)) .
