Chemistry - Thermodynamics - II Question with Solution | TestHub

The molar heat capacity $\left({\mathrm{C}}_{\mathrm{p}}\right)$ of ${\mathrm{CD}}_2\mathrm{O}$ is 10 cals at $1000\mathrm{K}$. The change in entropy associated with cooling of $32\mathrm{g}$ of ${\mathrm{CD}}_2\mathrm{O}$ vapour from $1000\mathrm{K}$ to $100\mathrm{K}$ at constant pressure will be: $(\mathrm{D}=$ deuterium, atomic mass $=2\mathrm{u})$
