One mole of an ideal gas at $300 \ K$ is expanded isothermally from an initial volume of $1 \ L$ to $10 \ L$. The change in internal energy for this process is ....... $cal$ $(R = 2 \ cal \ mol^{-1} \ K^{-1})$

The heat content of a system is called

Which of the following is an intensive property?

The relation between $\Delta E$ and $\Delta H$ is

When a system goes from state $A$ to state $B$,the change in internal energy is $40 \, kJ/mol$. If the system returns from state $B$ to state $A$ via a reversible path and then returns to state $A$ via an irreversible path,what is the net change in internal energy?

Heat exchanged in a chemical reaction at constant temperature and constant pressure is called as
