What is the first law of thermodynamics
If two objects A and B are in thermal equilibrium with a third object C, then A and B
Conservation of energy in thermal physics
The entropy of a perfect crystal at absolute zero is exactly equal to zero
Entropy of an isolated system can stay the same Conservation of energy in thermal physics or increase. It can never decrease.

what is the second law of thermodynamics?
The entropy of a perfect crystal at absolute zero is exactly equal to zero.
Entropy of an isolated system can stay the same or increase. It can never decrease. This is the 1st law of thermodynamics

Dalton’s Law = Rate of evaporation is dependent on the difference between:
ability of air to hold water
Energy in the water body (usually temperature) making it release water to the air
the amount of water
The amount of sunlight
