1.One mole of an ideal gas at temperature T1T_1T1 expands according to the law P=aP = aP=a (constant). The work done by the gas till the temperature of the gas becomes T2T_2T2 is:a.R(T2−T1)2\dfrac{R(T_2 - T_1)}{2}2R(T2−T1)b.R(T2−T1)R(T_2 - T_1)R(T2−T1)c.R(T2−T1)γ−1\dfrac{R(T_2 - T_1)}{\gamma - 1}γ−1R(T2−T1)d.R(T2−T1)γ\dfrac{R(T_2 - T_1)}{\gamma}γR(T2−T1)Login to continueOnly logged in users canattempt or see the solution.
