When `100J` of heat is given to an ideal gas it expands from `200cm^(3)` to `400cm^(3)` at a constant pressure of `3 xx 10^(5) Pa`. Calculate (a) the change in internal energy of the gas (b) the number of moles in the gas if the initial temperature is `400K`, (c ) the molar heat capacity `C_(p)` at constant pressure and (d) the molar heat capacity `C_(v)` at constant volume. `[R = (25)/(3)J//mol-K]`
