Question details

1. Use the Kelvin-Planck statement of the second law to show that the specified process is irreversible. (a) As shown in Figure 1.0, a hot thermal reservoir is separated from a cold thermal reservoir by a cylindrical rod insulated on its lateral surface. Energy transfer by conduction between the two reservoirs takes place through the rod, which remains at steady state. Hot reservoir 0 RodInsulation Figure 1.0 (b) As shown in Figure 2.0 a rigid insulated tank is divided into halves by a partition. On one side of the partition is a gas. The other side is initially evacuated. A valve in the partition is opened and the gas expands to fill the entire volume Insulation Initially filled with a gas Initially evacuated Volume V Volume-V Figure 2.0
