The first law states that energy is a system that can not be created or destroyed. Instead if you have a swimming pool and you say it got colder. That wouldn t be true. It could only get less warm. Law number two states that the warmth from the swimming pool is going to a place that is less warmer to make it warmer.
Heat moves in one direction.
If something is cold and it is put into a pot of boiling water all of the heat is going to go into what you put in there that is frozen. We use the sun to keep us warm at night and during the day. Our earth has heat to keep it going. We use nuclear energy every day for safety. Chemical reactions find new ways to live.
