Show that for 1 mole of an ideal gas `C_p-C_v=R`, where `C_p` and `C_v` have their usual meaning.

Define C_P and C_V

Show that for ideal gas C_(p)-C_(v) = R .

For a concave mirror, prove that 1/u+1/v=1/f , where u, v and f have their usual meanings.

Establish the formula v = u +at, where symbols have their usual meanings.

The pressure exerted by an ideal gas is p= 1/3 M/Vc^2 where the symbols have their usual meanings. Using standard gas equation, pV=nRT we find that c^2=(3RT)/M or C^2 prop T . Average kinetic energy of translation of 1 mol of gas= 1/2 Mc^2=(3RT)/2 At what temperature, when pressure remain unchanged , will the rms speed of a gas be half its value at 0^@C ?

In case of 1 mol of an ideal gas, write down the value of C_(v) - C_(p) .

In triangle ABC, if A - B = 120 and R = 8r , where R and r have their usual meaning, then cos C equals

Prove that C_(p) - C_(v) = R , where C_(p) and C_(v) are the molar specific heats at constant pressure and constant volume respectively and R is the universal gas constant.

Prove C_(p) - C_(v) = R
