Calculate the internal energy change for each of the following. (a) One hundred eleven (111) joules of work are required to compress a gas. At the same time, the gas releases 26 J of heat. WebAssign will check your answer for the correct number of significant figures. ad Incorrect: Your answer is incorrect. seenKey 85 J (b) A piston is compressed from a volume of 8.23 L to 2.75 L against a constant pressure of 1.88 atm. In the process, there is a heat gain by the system of 360. J.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
