How much work can be done by 100 calories of heat?

How much work can be done by 100 calories of heat?

An engine is working . It takes 100 calories of heat from source and leaves 80 calories of heat to sink . If the temperature of source is 127^(@) C, then temperature of sink is

The work done by 100 calorie of heat in isothermal expansion of ideal gas is :-

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) ?
