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 $, J$)? $(1 \, L \cdot atm = 101.3 \, J)$

An ideal gas undergoes a cyclic transformation starting from the point $A$ and coming back to the same point by tracing the path $A$ $\rightarrow B$ $\rightarrow C$ $\rightarrow D$ $\rightarrow A$ as shown in the three cases above. Choose the correct option regarding $\Delta U$.

The law of $Lavoisier$ and $Laplace$ illustrates:

On what factors does the enthalpy of dilution of a solution depend?

Consider the reversible isothermal expansion of an ideal gas in a closed system at two different temperatures $T_1$ and $T_2$ $(T_1 < T_2)$. The correct graphical depiction of the dependence of work done $(|w|)$ on the final volume $(ln V)$ is:

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