Isothermal curves for a given mass of gas are shown at two different temperture `T_(1) and T_(2)` in Fig. State whether `T_(1) gt T_(2) or T_(2)gt T_(1)`. Justify your answer.

Explanation

Keeping the pressure of the gas remains constant.
According to Charles's law `V prop T`

In the graph is pressure kept constant and volumes are comapred
From Charles's law at constant pressure `V prop T`
From the graph `V_(2) gt V_(1)` so `T_(2) gt T_(1)`
