Calculate the difference between the two molar specific heats of a gas, given J= 4200 J/k cal and one kilomole of gas occupies 22.4 litres at N.T.P.

Prove that gram molecular mass of any gas occupies 22.4 litre at NTP .

Calculate the number of molecules in one litre of gas at N.T.P. if mass of each molecule is 4.55xx10^(-25) kg and its R.M.S velocity at NTP is 350 m/s.

Calculate the RMS velocity of oxygen molecule at 27^@C . Given 1 atom= 2.013xx10^5 N/m^2 , m= 32, molar volume 22.4 litre.

Calculate the temperature at which oxygen gas at one atmospheric pressure has the same R.M.S velocity as that of Nitrogen at N.T.P.

A metal rod 25 cm long and 10sq cm in cross section has it's one end placed in boiling water and the other end in melting ice. Calculate the mass of ice method per minute if K for metal is 378 W/mk. Latent heat of fusion of ice - 80 K cal/gm . J = 4200 j/Kcal.

Define molar specific heat and explain why a gas has two specific heats. Deduce the relation C_p - C_V=R , when the symbol carry their usual meaning.
