In thermodynamic process pressure of a fixed mass of gas is changed in such a manner that the gas releases $30$ joule of heat and $18$ joule of work was done on the gas. If the initial internal energy of the gas was $60$ joule, then, the final internal energy will be ..... $J$

$1\ cc$ of water at its boiling point $(100^o\ C)$ is converted into steam by supplying it $540\ calories$ of heat the volume of steam is $1671\ cc$. If atmospheric pressure is $1.013 × 10^ 5\ Nm^{-2}$ and $J = 4.18\ joule/cal$ the approximate value of heat that is required in overcoming the molecular attraction is ........ $cal$
