Chemistry - Thermodynamics - 1 Question with Solution | TestHub

Heat absorb during a change of state ( $\mathrm{P},{\mathrm{V}}_1,{\mathrm{T}}_1$ ) to ( $\mathrm{P},{\mathrm{V}}_2,{\mathrm{T}}_2$ ) in a closed system involving ideal gas must be equal to $\Delta \mathrm{H}$.

Heat exchanged during a reversible isothermal process between two fixed states is a difinite quantity.

Complete conversion of heat into work is not possible in a reversible isothermal expansion of ideal gas.
