Identify the process from the following such that the volume of the system remains constant.

Identify the process having $\Delta V = 0$.

If $5 \ mol$ of an ideal gas expands from $10 \ L$ to a volume of $100 \ L$ at $300 \ K$ under isothermal and reversible conditions,then the work done,$w$,is $-x \ J$. The value of $x$ is $ . . . . . . $. (Given $R = 8.314 \ J \ K^{-1} \ mol^{-1}$)

The internal energy of a substance $U$ is related to temperature $T$ in which of the following ways?

For the process $CO_{2(s)} \rightarrow CO_{2(g)}$,which of the following is true?

The work done when the temperature of $1 \, \text{mol}$ of an ideal gas is increased by $2 \, ^\circ\text{C}$ is ......... $J$.
