Argon gas has several industrial uses, including arc welding and steel making. Argon is nonflammable and nontoxic, and so can be kept at room temperature (T = 21° C). Companies can buy Argon gas in cylinders which are kept at pressure of P = 221 psi. In this problem you may assume that ideal gas law still holds. Part A:  How much average kinetic energy (in J) does each atom of the the Argon gas in the cylinder have?  Part B:  If the volume of this cylinder is V = 179 L, how many moles of Argon are inside?

An ideal gas initially at p= 1.69 atm, V= 1.24 L and T= 31.2 ∘C is expanded under constant pressure to a final volume of 2.93 L. A. What is the final temperature of the gas? B. How much work is done on the gas?

Given that the gas pressure is 3500Pa and there are 4.8x10^20 gas molecules in the cylinder, answer the following: A.) Then 2.5 J of heat energy is transferred to the gas. What is the new equilibrium temperature of the gas in °C? B.) What is the final height of the piston? C.) How much work is done on the gas as the piston rises?

A cylinder filled with ideal gas has a piston of mass M=5kg and area A=10 cm?. The cylinder has a valve located at the bottom. The valve was initially opened and some of the gas escapes slowly. The valve is then closed, after which the piston is observed to be at a lower position. Assume that the system is in thermal equilibrium with the surroundings and the piston is allowed to move freely during the whole process. 1. What was the initial absolute pressure of the ideal gas before the valve was opened? Is the final pressure of the gas in the cylinder greater than, less than, or equal to the initial pressure? Explain. Explain how your answer is consistent with the forces acting on the piston in the initial and final states.

Consider the two-sided chamber shown, where the right side has a volume of V and the left side 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 and temperature T. The seal between the two sides is then opened. a If the temperature in the chamber is decreased by a factor of 2 by a refrigeration system while the gas fills the chamber, give an expression for the new pressure P' in terms of the original pressure P.   b) The chamber is then sealed again, trapping 2/3 of the gas molecules in the left side. The temperature of the left side is then doubled by a heater, back to the original temperature T. What is the pressure in the left side of the chamber now, in terms of the original pressure?
