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

From ideal gas equation
`PV = mu RT`
`T= (PV)/(mu R)`
As mass of gas is constant, `mu` is constant , R already a constant.
`:. T prop PV`
Since PV is greater for the curve at `T_(2)` than for the curve at `T_(1)`, therefore, `T_(2) gt T_(1)`.
