According the second law of thermodynamics, which of the following applies? USE IMAGE AS REFERENCE Question 4: You have a heat engine operating in a complete cycle. According the secondlaw of thermodynamics, which of the following applies?A) The thermal energy received from a high temperature reservoir equals the entropy increase.B) The thermal energy received from a high temperature reservoir is completely converted intowork.C) Some of the thermal energy received has to be damped into a lower temperature reservoir.D) The internal energy increases.

Let's check each option one by one A) the thermal energy received from high temperature reservoir equals the entropy increase Incorrect option dQ = T dS Entropy and Heat have different units. They cannot be same.B) the thermal energy receive from a high temperature reservoir is completely converted into work Incorrect option This Statement violates the second law of thermodynamics which states the no cyclic process is possible whose sole result is complete conversion of heat into work. C) some of the thermal energy received has to be damped into a lower temperature reservoir. Correct option . This statement is in accordance with second law of thermodynamics. Heat is not completely converted into work in cyclic process some of the heat is given to the surrounding. D) The internal energy increases Incorrect option In cyclic process system returns to its initial stage and internal energy is a state function. Hence change in internal energy is zero.
