the diagram is being used to illustrate the second law of thermodynamics, where qh represents a hot object and qc represents a cold object.

answer: second law: some thermal energy is lost to the surrounding environment as it travels through the system. the diagram is being used to illustrate the second law of thermodynamics, where qh represents a hot object and qc represents a cold object. a)energy must be destroyed for entropy to be constant.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
