Answer . Calculate the internal energy change for each of the following. a. One hundred (100.) joules of work is required to compress a gas. At the same time, the gas releases 23 J of heat. b. A piston is compressed from a volume of 8.30 L to 2.80 L against a constant pressure of 1.90 atm. In the process, there is a heat gain by the system of 350. J. A piston expands against I 1037 J of heat...

One mole of a dilute gas initially has a pressure equal to 1.00 atm, and a volume equal to 21.0 L and an internal energy of 3.19 kJ. As the gas is slowly heated, the plot of its state on a PV diagram moves in a straight line to the final state. The gas now has a pressure equal to 3.00 atm, and a volume equal to 74.0 L, and an internal energy equal to 33.7 kJ. (a) Find the...

One mole of an ideal mono-atomic gas is in a state A characterized by a temperature TA. The gas is then subjected to a succession of three quasi-static reversible processes: An isothermal expansion A → B, which increases the volume by a factor y. The expansion factor is therefore y = VB / VA> 1. An adiabatic compression B → C which increases the pressure by a factor w. The compression factor is w = pC / pB> 1. A...

Please explain.
Which statement is true? A state function is one whose value for a system is determined by the temperature of the system, and not on the composition of the system. A state function is one whose value for a system depends on the method of preparation of the reactants and products. A state function is one whose value for the system is determined by only the pressure of the system, and not on the temperature of the system....

A monatomic ideal gas is taken through a closed cycle. Starting from state 1 with pressure P1 and volume V1 the gas expands isothermally (at constant temperature) to volume V2 = 2V1. It is then compressed at constant pressure back to the original volume V1 and then heated at constant volume to return to the original pressure P1 . a) Find how much work is performed by this gas during each part of this cycle. b) Find how much heat...
