First and second laws of thermodynamics?

Answer 1

First Law of Thermodynamics: Energy can be converted from one form to another, but cannot be created or destroyed.

Second Law of Thermodynamics: The second law of thermodynamics states that for any process occurring in a closed system, the entropy increases for an irreversible system and remains constant for a reversible system, but never decreases.

Answer 2

The first law of thermodynamics is: Energy cannot be made or destroyed. But heat energy can be used to power movement energy, and movement energy can turn into heat energy.

The second law of thermodynamics is: Heat energy always moves from hot things to cold things (this is why the sun will heat up cold lemonade if the lemonade is left outside on a hot day).

Answer 3

The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, and that natural processes tend to move towards a state of higher entropy.
