an ideal gas undergoes a single stage expansion against a constant opposing pressure from (P1,V1,T) to(P2,V2,T).what is the largest mass m which can be lifted through a height h in the expansion?the answer does nat have p ext ,so i am confused.

Question

Chetan Mandayam Nayakar · Answer

work done=nRTln(V2/V1)=mgh

anushka shanbhag · Answer

the answer is wrong.external pressure is constant so u cannot apply reversible process equation.

Sarthak Shrivastava · Answer

askIITians your IITians have provided a wrong answer. The external pressure will be P2. Hope with this you will be able to solve with this information

Aastha · Answer

Work done = mgh=Pext(nRT/P 2 -nRT/P 1 ) Given:exp n against constt.pressure.....irreversible process Pext=P final =P 2 So, m=nRT/gh(1-P 2 /P 1 )
