(5) Write the first law for a closed system, steady form, ignore kinetic and potential energy. (does it use enthalpy or internal energy?) (6) Write the equation to evaluate the work for a closed system (p-v work) for processes where po" = constant. (7) What is the name of a reversible power cycle? What can you assume about the efficiency of this cycle?

Second Law of Thermodynamics Learning Goal: To understand the implications of the second law of thermodynamics. The second law of thermodynamics explains the direction in which the thermodynamic processes tend to go. That is, it limits the types of final states of the system that naturally evolve from a given initial state. The second law has many practical applications. For example it explains the limits of efficiency for heat engines and refrigerators. To develop a better understanding of this law,...

Law of Gauss 1. Consider a constant vector field of the form v = (1, 1, 1)N/C and a closed area with cubic shape of side 1m oriented as desired. a) What is the flow of v through the cube? b) If now a point load of 1C is introduced into the cubic surface. What will be the total electric field flow through the cube? (Note step by step)

The first law of thermodynamics D. The cylinder, with the piston still locked in place, is now immersed in a mixture of ice and water and allowed to come to thermal equilibrium with the mixture. The piston is then moved inward very slowly. in such a way that the gas is always in thermal equilibrium with the ice-water mixture. We will refer to this slow compression of the gas as process 3. 1. During process 3, do the following quantities...
