What is calorimetry?

In thermodynamics,a process is called reversible when

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

One mole of a non-ideal gas undergoes a change of state ($2.0 \, atm$,$3.0 \, L$,$95 \, K$) $\rightarrow$ ($4.0 \, atm$,$5.0 \, L$,$245 \, K$) with a change in internal energy,$\Delta U = 30.0 \, L \, atm$. The change in enthalpy $\Delta H$ of the process in $L \, atm$ is.

Which of the following expressions is true for an ideal gas?

The number of extensive and intensive properties in the list given below is respectively: density,enthalpy,mass,temperature,volume,pressure.
