An ideal gas with energy U and N atoms is held in one-half of a chamber of volume V by a partition (refer Figure 1(A)). As the partition is removed and the gas in the container is allowed to occupy the entire volume V, an additional N atoms of the same gas with the same energy U is introduced into the container as shown in Figure 1(B). . Nu, V/2A) Figure 1 1. What is the initial entropy (S) of...

Consider an insulated container of volume V2. N ideal gas molecules are initially confined within a sub-volume (V1) by a piston and the remaining volume V2 - Viis in vacuum. Let T., P., U1, S1, A1, H1, and G1 be the temperature, pressure, internal energy, entropy, Helmholtz free energy, enthalpy, and Gibbs free energy of the ideal gas at this state, respectively. Now, imagine that the piston is removed so that the gas has volume V2. After some time...

2. 10 points Consider a thermally isolated system consisting of two volumes of an ideal gas separated by a thermally conducting movable partition, which is initially fixed. Initially, the temperatures, pressures, and volumes of the two parts are P, V, T and 3P, 2V, and T respectively (see figure below). The partition is now allowed to move without gases mixing, until the equilibrium is reached. a) What is the change of the internal energy of the system after the equilibrium...

A vertical cylinder contains N atoms of an ideal gas and is closed off by a piston having mass m and area a. The acceleration due to gravity is g. The gas has a heat capacity Cy which is independent of temperature. (Note that the preceding sentence contains the words "heat capacity" and does not contain the words "specific heat.") Neglect the heat capacity of the cylinder and piston, ignore friction, and the entire system is thermally insulated. The piston...
