Two moles of a gas with a constant‑volume molar specific heat of 20.8 J / ( mol ⋅ K ) is transformed from state A, with temperature T I = 291 K, to state B, with temperature T F = 327 K, as shown in the diagram. What was the change in the entropy ΔSΔS of the gas?
Two moles of oxygen gas are contained in a piston and cylinder device. Initially the gas is at 300. K and sufficient weight is placed on the piston so that the pressure is 2.0 bar. Consider two different processes in which 2000. J of energy in the form of heat are added to the gas in the device. In the second process, the piston is allowed to move freely so that the pressure remains constant. What are the final temperature...

Please answer the two blank boxes! A heat engine with 0.227 moles of a monatomic gas undergoes the cyclic procedure shown in the pV diagram on the right. Between stages 3 and 1 the gas is at a constant temperature, and between 2 and 3 no heat is transferred in or out. The temperature of the gas at stage 2 is 375 K. kPa What is the type of each process in the cycle? Between 1 and 2 isisochoric Between...
3.5 moles of oxygen (O2) gas are at a pressure of 7.3 atm and of 22 L. The gas then expands to a new volume of 86 L Find done by the gas, the heat added to the gas, and the change in the internal energy of the gas for each of the following two cases: a) The expansion of the gas occurs at constant temperature. b) The expansion of the gas is adiabatic.
Help 404 J of energy is transferred to a system consisting of 2.0 moles of an ideal gas. If the volume of this gas stays at a constant 2.4 L, calculate the change in internal energy of the gas.
An engineering professor adds 1.60x104 J of heat at constant volume to 2.70 moles of N2 gas that is initially at 1.00 atm and 15°C. The esteemed professor then continues to add heat allowing the gas to expand at constant pressure to 1.9 times its volume. Determine the final temperature of the gas
Under constant-volume conditions, 3100 J of heat is added to 1.9 moles of an ideal gas. As a result, the temperature of the gas increases by 78.5 K. How much heat would be required to cause the same temperature change under constant-pressure conditions? Do not assume anything about whether the gas is monatomic, diatomic, etc.
Under constant-volume conditions, 4100 J of heat is added to 1.5 moles of an ideal gas. As a result, the temperature of the gas increases by 132 K. How much heat would be required to cause the same temperature change under constant-pressure conditions? Do not assume anything about whether the gas is monatomic, diatomic, etc.
