Select the appropriate law for each description:
some energy is released as unusable heat energy into the environment.
energy can only be changed from one form to another.
energy can't be created or destroyed.

The appropriate law for each description is as follows;  

Some energy is released as unusable heat energy into the environment - Second law of thermodynamics.

Energy can only be changed from one form to another - First law of thermodynamics.

Energy can't be created or destroyed – First law of thermodynamics.

The first law of thermodynamics, also referred to as law of conservation of energy, states that energy cannot be created or destroyed, but can only be converted or transferred from one form to another.

The second law of thermodynamics states every energy transfer that occur will increase the overall entropy of the universe and minimize the amount of usable energy available to do work.
