Chemistry - Thermodynamics - I Question with Solution | TestHub

A gas expands from a volume of $3{\mathrm{dm}}^3$ to $30{\mathrm{dm}}^3$ against a constant pressure of 7 bar at initially $27^{\circ }\mathrm{C}$. The work done during expansion is used to heat, 50 moles of water. Calculate rise in temperature ( K ) of water (Take specific heat capacity of ${\mathrm{H}}_2\mathrm{O}$ is $4.2\mathrm{J}/$ gram.K \& 1 litre bar $=100\mathrm{J}$ )
