Question

In a certain themodynamical process, the pressure of a gas depends on its volume as kV^3. The work done when the temperature changes from 100^ C to 300^ Cwill be_____ nR, where n denotes number of moles of a gas.

Accepted Answer

Correct answer: 50. 50 JEE Main 2021 P=kv^3 pv^-3=k x=-3 w= nR(T_1-T_2)x-1 = nR (100-300 )-3-1 = nR (-200 )-4 =50 nR

$In a certain themodynamical process, the pressure of a gas depends on its volume as kV^{3} . The work done when the temperature changes from 100^{\circ} C to 300^{\circ} C will be_____nR, where n denotes number of moles of a gas.$
