Answer:
C
Step-by-step explanation:
The law of constant heat states that no matter how many steps are in a reaction, the total enthalpy change is the sum of all changes. Therefore, this is not correct.
The kinetic theory models the thermodynamic properties of gases. So this is not the correct choice.
The law of conservation of energy states that the energy remains constant. Basically, it isn't created or destroyed, it simply transforms. This is the correct choice.
C. The law of conservation of energy is correct.
