You can find two kinds of change in matter: chemical change and physical change. As the names suggest, chemical changes affect chemical properties and physical changes affect physical properties.
Chemical changes are also called chemical reactions. The end results are referred to as the products and the ingredients of a reaction are the reactants. The change from reactants to products can be signified by an arrow.

When changes take place, energy is frequently transformed.
However, such as atoms, energy cannot disappear. This is known as the Law of
Conservation of Energy. An easy example would be putting ice cubes into a soft
drink. The ice cubes get hotter as the drink gets cooler, because energy cannot
be destroyed or created, only transferred.
Changes of States of Matter
All matter can shift from one state to another. It may need
extreme pressures or extreme temperatures, however it can be done. Occasionally
a substance does not want to change states. You have to utilize all of your
tricks when that takes place. To produce a solid, you might have to reduce the
temperature by a massive amount and then add pressure.
Phase changes occur when certain
points are reached. Occasionally a liquid wants to become a solid. Scientists
use something referred to as a freezing point to calculate the temperature
where a liquid becomes a solid. You can find physical effects that can alter
the freezing point. Pressure is one of those effects. When the pressure
encircling a substance goes up, the freezing point and other special points
also rise. Meaning it's easier to maintain things solid at higher pressures.
