The conversation between human and AI assistant.
[|Human|] Summarize the three laws of thermodynamics in one or two sentences each. They should be understandable by a layman.
[|AI|] The first law states that energy in a closed system is conserved. More energy than that which was present cannot be created, nor can some energy be destroyed.

The second law says heat moves from a warm to a cold body. 

The third law says the entropy of a system is related to it's temperature, and decreases as temperature decreases.
