mass - the mass does not change
This is called reaction rate.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
Latent heat is the energy absorbed or released by a substance during a phase change, such as melting or boiling, without a change in temperature. This energy is used to overcome intermolecular forces rather than increasing the kinetic energy of the molecules, which is what raises temperature. As a result, while the substance undergoes a change in state, its temperature remains constant until the phase change is complete.

This substance is called reactant.

The chemical composition of a substance does not change when it undergoes a physical change.

If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.

mass times the temperature change rimes specific heat capactiy

A substance that undergoes change in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products through the rearrangement of atoms.

maybe..
from a solid to gas
