When a chemical substance is transformed as a result of its interaction with another substance or with energy, a chemical reaction is said to have occurred.
A phase is a set of states of a chemical system that have similar bulk structural mr taxi allison veltz properties, over a range of conditions, such as pressure or temperature.
