The second law of thermodynamics states that
a. we can get more out of a process than we put in.
b. we cannot get more out of a process as we put in.
c. we can get out of a process exactly when we put in.
d. two bodies are in thermal equilibrium when they both have the same temperature. e. work and temperature are the same thing.
Homework Answers
No engine has ever been developed that can convert the amount of heat supplied completely into work without rejecting any heat to lower temperature. This constitute 2nd law.
So, answer (b) is correct. (b) we can not get more out of a process as we put in.

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,...

The first law of thermodynamics In thermal physics, we are often interested in the internal energy (E) of a system. The wo 41 internal energy of an ideal gas is proportional to the temperature and the number of moles of the gas. The internal energy can change when energy is exchanged with the system's environment (ie., objects that are outside the system of interest). The case above is one in which the internal energy of a gas changes due to...

The first law of thermodynamics states that energy can neither be created nor destroyed. How then is it possible for ∆E to be anything other than zero? In other words, what do we mean when we call a physical scenario “non-conservative” if energy must, by nature, be conserved?

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...
