Figure 1 shows the initial state of an apparatus consisting of an ideal gas in a bulb, a stopcock, a porous plüg, and a cylinder containing a frictionless piston. The walls are diathermal, and the surroundings are at a constant temperature of 300:0K and a constant pressure of 1:00 bar. When the stopcock is opened, the gas diffuses slowly through the porous plug, and the piston moves slowly to the right. The process ends when the pressures are equalized and the piston stops moving. The system is the gas. Assume that during the process the temperature throughout the system differs only infinitesimally from 300:0K and the pressure on both sides of the piston differs only infinitesimally from 1:00 bar. Calculate q and w

Question

Figure 1 shows the initial state of an apparatus consisting of an ideal gas in a bulb, a stopcock, a porous plüg, and a cylinder containing a frictionless piston. The walls are diathermal, and the surroundings are at a constant temperature of 300:0K and a constant pressure of 1:00 bar. When the stopcock is opened, the gas diffuses slowly through the porous plug, and the piston moves slowly to the right. The process ends when the pressures are equalized and the piston stops moving.

The system is the gas. Assume that during the process the temperature throughout the system differs only infinitesimally from 300:0K and the pressure on both sides of the piston differs only infinitesimally from 1:00 bar.
