FIRST LAW OF THERMODYNAMICS *the total heat energy applied to the system is equal to the sum of the change in internal energy of the system and the work done by the system.
SECOND LAW OF THERMODYNAMICS (entropy) *no process in w/c the total entropy decreases is possible when all the systems taken apart in the process are considered.
BONUUUUSSS :D
THIRD LAW OF THERMODYNAMICS *The entrophy of a perfect crystal of a substance at the absolute temp. is zero.
I hope this helps! <3
