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

Calculate the work done in joule if $2 \ mol$ of an ideal gas expands isothermally from $15.5 \ dm^3$ to $20 \ dm^3$ at a constant external pressure of $1 \ atm$. (in $J$)

In which of the following reactions is $\Delta E = \Delta H$?

For a reversible process at $T = 300 \, K$,the volume increases from $V_i = 1 \, L$ to $V_f = 10 \, L$. If the process is isothermal,find the value of $\Delta H$ in $kJ$.

The formula for the Joule-Thomson coefficient is ............. .

What are extensive properties?
