A graph is plotted between pressure and volume at different temperatures. On the basis of the graph what changes will you observe in the volume if
(i) the pressure is increased at constant temperature.
(ii) the temperature is decreased at constant pressure.

Dear Student,

From the given graph observation it has been found,

1. By increasing pressure at constant temperature we get reduced (or) decrease in volume. P α 1V

2. By reducing temperature at constant temperature results in increase of volume. V α 1T

Regards.
