$1 \, mol$ of an ideal gas is compressed reversibly at a constant temperature of $27 \, ^oC$ from $1 \, bar$ to $4 \, bar$. Calculate the work done in $kJ$.

One mole of a gas expands from $1 \, L$ to $5 \, L$ against a constant external pressure of $1 \, atm$. How much work is done in Joules (in $, J$)? $(1 \, L \cdot atm = 101.3 \, J)$

Identify the pair in which both are not extensive properties.

Heat exchanged in a chemical reaction at constant temperature and constant pressure is called as

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

Calculate work done in isothermal reversible expansion of $1 \ mol$ of an ideal gas from an initial pressure of $10 \ bar$ to a final pressure of $1 \ bar$ at $300 \ K$ $\left(R = 8.314 \ J \ K^{-1} \ mol^{-1}\right)$. (in $kJ$)
