That would be the law of conservation of mass, conservation of matter.
The First Law of Thermodynamics
no
No, the Law of Conservation of Energy (a.k.a. First Law of Thermodynamics) states that energy CAN NOT be created or destroyed. Converting energy to a less valuable form is related to the Second Law of Thermodynamics.
Mass is never lost nor gained - neither in chemical reactions, nor in other cases.
Vaporization is an endothermic process. It takes energy to heat up material to the point that it vaporizes, so energy is gained by the material being vaporized and lost by the environment.
there is an increase in entropy in the universe.
The Law of Conservation of Energy states that energy is neither created nor destroyed but remains constant in a given system. Therefore, wouldn't calorimetry make use of it because the energy gained/lost by the water would cancel out the energy lost/gained by the substance and result in no change overall?

When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.

90 % is lost.
When a substance evaporates, it gains energy.
Some energy is changed to heat and lost. The main energy is still be converted to light beam.
Condensation is exothermic. Energy is released during condensation. Energy can not be "lost" but merely change from one form to another.
