Explanation: In heat engine cycle, the heat is transferred to the system and work is transferred from the system. When two bodies are brought in physical contact with each other and one body has more temperature than other then hear transfer takes place from hot body to cold one. When work is done by a system then it is taken as positive, and when work is done on the system by the surrounding then it is taken as negative. 0/41 Questions. Core 0%. If the system as a whole is at rest, so that the bulk mechanical energy due to translational or rotational motion is zero, then the Temperature is the term through which we can differentiate between hot and cold. on his final exams.
