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

`T=(PV)/(muR)`, `TalphaPV` [`muR=` constant]
Since `PV` is greater for the curve at `T_(2)` than for the curve `T_(1)` therefore `T_(2) gt T_(1)`.
