The number of extensive and intensive properties in the following list is respectively: Mass,temperature,pressure,enthalpy,heat capacity,internal energy,density.

Identify the equation in which the change in enthalpy is equal to the change in internal energy.

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 $kJ$.

For an endothermic process,$\Delta H$ will be ...... .

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

When $2$ moles of an ideal gas are expanded isothermally from a volume of $12.5 \ L$ to $15.0 \ L$ against a constant external pressure of $760 \ mm \ Hg$,calculate the amount of work done in joules. (in $J$)
