If 96.5 mol of an ideal gas occupies 97.5 L at 93.00 °C, what is the pressure of the gas? Heliox is a helium-oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 7.25-L tank holds helium gas at a pressure of 1563 psi. A second 7.25-L tank holds oxygen at a pressure of 415.6 psi. The two gases are mixed in a 7.25-L tank....

Joule Joule -_ Joule Joule cylinder with 20 g of nitrogen gas is mechanically coupled to the environment with a frictionless piston The initial pressure is 1 atm and the initial temperature is 20°C. The gas is then reversibly compressed to half of its initial volume in an isothermal process. Calculate the heat q, work w, change in internal energy ΔU and change in enthalpy ΔH for this process in Joule. You can assume ideal behavior for the nitrogen gas
