- Problem 1: Consider the two-sided chamber shown,where the right half has a volume of V = 590 L and the left half has a volume of 2V. The chamber has a seal which separates the right from the left half. The chamber is sealed and an ideal gas is pumped into the right side at a pressure P= 6.4 atm and temperature T= 78° C. The seal between the two sides is then opened. 2V V Part (a) If the physical temperature decreases by a factor of 2 while the gas fills the chamber, what is the new pressure, in kilopascals?

- Problem 2: Helium is a very important element for both industrial and research applications. In its gas form it can be used for welding, and since it has a very low melting point (only 0.95 K under 2.5 MPa) it can be used in liquid form to cool superconducting magnets, such as those found in particle physics experiments. Say we have a cylinder of n = 145 moles of Helium gas at room temperature (T = 20° C). The cylinder has a radius of r = 17.5 cm and a height h = 1.45 m. Part (a) What pressure (in kPa) is the helium gas under? P = ______ Part (b) Helium is usually kept in the highest pressure gas cylinders, which can typically withstand at least 500 atm of pressure. Would the tank in part (a) be able to maintain its structural integrity? Part (c) In principle, these tanks could fail if the temperature of the Helium started rising - if they were stored in a hot environment, for instance. To determine how much of a danger this is, calculate the temperature (in C) the Helium gas…Calculate the standard enthalpy of hydrogenation of liquid benzene from its standard enthalpy of combustion (-3268 kJ mol-1) and the standard enthalpy of combustion of liquid cyclohexane (-3920kJ mol-1)Cp and Cy are specific heats at constant pressure and constant volume, respectively.
