$1$ mole of a diatomic gas is heated through an isochoric process from $300\,K$ to $500\,K$. The change in entropy is: (in $,J/K$)

What is the melting point of benzene if $\Delta H_{fusion} = 9.95 \ kJ/mol$ and $\Delta S_{fusion} = 35.7 \ J/K \cdot mol$?

Two blocks of the same metal having same mass and at temperatures $T_1$ and $T_2$ respectively,are brought in contact with each other and allowed to attain thermal equilibrium at constant pressure. The change in entropy,$\Delta S,$ for this process is

What is meant by absolute entropy?

At the boiling point of water,$900 \ J/g$ of heat is exchanged. What is the increase in entropy in $J \ K^{-1} \ mol^{-1}$?

The entropy change involved in the isothermal reversible expansion of $2 \, \text{mole}$ of an ideal gas from a volume of $10 \, dm^3$ to a volume of $100 \, dm^3$ at $27 \, ^oC$ is : .............. $J \, K^{-1}$
