Question

5. Consider the following piston-cylinder arrangement which is thermally insulated. Initially, the same 1 mole of monoatomic ideal gas are confined in the cylinder A and B respectively which are partitioned by a thermally conducted metal plate as shown in Figure 1. The initial volume and absolute temperature (X) of two partitions are the same as V and T respectively and the external pressure of the cylinder is given by P, as shown in Figure 1. When heat (g) was gradually supplied to B, the gas of A was expanded until the volume of v, under the constant external pressure of P. and t was then reached at the final equilibrium as shown in Figure 2. (Suppose that any possible temperature dependence of the heat capacity is negligibly smal In addition, assume that the friction betwoen the cylinder and the piston and the mass of the piston are ignored. The heat capacity of a thermally conducted metal plate is also ignored.) Thermally Insulated cylinder Thermally Insulated piston P, P, V. T, Figure 1 Figure 2 Metal Plate What is the value of PV.
