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

A gas has molar heat capacity C = 37.55 J "mole"^(-1)K^(-1) , in the process PT = constant, find the number of degree of freedom of the molecules of the gas.

An ideal gas having initial pressure p, volume V and temperature T is allowed to expand adiabatically until its volume becomes 5.66V, while its temperature falls to T//2 . (a) How many degrees of freedom do the gas molecules have? (b) Obtain the work done by the gas during the expansion as a function of the initial pressure p and volume V. Given that (5.66)^0.4=2

Which of the following expressions is correct ( n = no . of moles of the gas, N_(A) = Avogadro constant m = mass of 1 molecule of the gas, N = no of molecules of the gas) ? .

Assertion : The ratio C_(P)// C_(upsilon) for a diatomic gas is more than that for a monoatomic gas. Reason : The moleculess of a monoatomic gas have more degrees of freedom than those of a diatomic gas.

A gas has volume V and pressure p . The total translational kinetic energy of all the molecules of the gas is

The rms speed of helium gas at 27^(@)C and 1 atm pressure is 900 ms^(-1) . Then the rms speed of helium molecules at temperature 27^(@)C and 2 atm pressure is

A gaseous mixture enclosed in a vessel of volume V consists of one gram mole of gas A with gamma = (C_(P))/(C_(V)) = (5)/(3) an another gas B with gamma = (7)/(5) at a certain temperature T . The gram molecular weights of the gases A and B are 4 and 32 respectively. The gases A and B do not react with each other and are assumed to be ideal. The gaseous mixture follows the equation PV^(19//13) = constant , in adiabatic process. Find the number of gram moles of the gas B in the gaseous mixture.
