The second law of thermodynamics deals with the transfer of a. only work. b. momentum. c. heat. d. only pressure.

Step-by-step solution

The second law of thermodynamics establishes the direction of heat transfer and the limitations on converting heat into work. It states that heat cannot spontaneously flow from a colder body to a hotter body without external work being done. It also implies that it is impossible to construct an engine operating in a cycle that completely converts heat from a single reservoir into an equivalent amount of work. Thus, the second law of thermodynamics primarily deals with the transfer of heat. Answer: c
