H5-1. 80 g of ideal Argon gas (Ar) are at a 1000 L cylinder and constant temperature of 300 K.The system is closed by a free moving, frictionless piston, and above it there is a weight withmass M applying pressure as shown in the figure. At a certain moment a second weight is addedabove with identical mass M and the system is compressed until new equilibrium is reached.MW,Pin VinT = constMMWMMPin VinP₁ V₁T = constT = consta. Calculate the work and the change in the internal energy of the Argon gas as a result of thecompression process, given Q = - 4.99 kJ, Mw(Ar)= 40 g.mol-1.b. One weight is removed and the system returns to the original state, as described in thefigure. Calculate the for the entire process the work and change in internal energy.
