Calculate the internal energy change for each of the following. a. One hundred (100.) joules of work are 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. c. A piston expands against 1.00 atm of pressure from 11.2 L to 29.1 L. In the process, 1037 J of heat is absorbed.
Discuss how the phase equilibria of mixtures are represented using diagrams similar to the pressure-temperature and pressure-specific volume diagrams for one- component systems. Use the example of a mixture of ethane and heptane to illustrate your..
