How would you explain isothermal expansion?

Isothermal expansion refers to the plot of a pressure versus volume diagram held at a constant temperature that shows the volume increasing.

Explanation:

An isothermal process refers to a change of a system, in which the temperature remains constant (Delta T =0).

The graph above shows a pressure vs. volume graph (called an isotherm). During an expansion, the final volume becomes larger than the initial volume, which is indicated by the purple arrow going in the forward (rarr) direction.
