Question

Quizplus · Accepted Answer

The mechanical equivalent of heat concept is based on the principle that heat and mechanical energy can be converted into each other. This is demonstrated by all the statements given: thermal energy can be converted into mechanical energy (A), mechanical energy can be converted into thermal energy (B), work (a form of energy) can be converted into thermal energy (C), and some thermal energy can be converted into work (D). Therefore, all the options correctly contribute to the concept of the mechanical equivalent of heat.
