Answer:

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.
