How many calories of heat are required for external work when one gram mole of a as is heated by `1^(@)C` at constat pressure?

How many calories of heat are required to compltely evaporate 1 g of ice at 0^@C ?

To raise the temperature of a certain mass of gas by 50^(@)C at a constant pressure , 160 calories of heat is required . When the sam mass of gas is cooled by 100^(@)C at constant volume 240 calories of heat is released . How many degrees of freedom does each molecule of this gas have (assume gas to be ideal) ?
