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...
The air within a piston equipped with a cylinder absorbs 555 J of heat and expands from an initial volume of 0.11 L to a final volume of 0.88 L against an external pressure of 1.0 bar. What is the change in internal energy of the air within the piston?

A system contracts from an initial volume of 15.0 L to a final volume of 10.0 L under a constant external pressure of 0.800 atm. The value of w, in J, is A) -4.0 J. 10-15 =-SL...
Calculate the work done by a system when it expands against a constant external pressure of 4.6 atm from an initial volume of 6.9 L to a final volume of 21.6 L. Give your answer in joules (J) to the nearest integer (whole number). Do NOT input units. If your answer is negative, use a hyphen - (do not use an underscore) and do not add any spaces. For example, if your answer is -345.678 J, enter -346
400 J of heat is added to a system. If the change in internal energy of the system was 850 J, how much work was done on by the system? the inside a container absorbs 250 J of hea while 125 J of work is done on it and then does 70 J of its own work, by how much does the internal energy of the gas increase? 7.500 joules of heat is added to a system while it also...
