This is actually known as the fourth state of matter which is the<em> plasma</em>. The plasma is basically a hot ionized gas. It consists of equal number of protons and electrons. This can be obtained by subjecting a gas to a high energy, for example, a laser beam. The energy from the laser beam causes a rapid energy increase of the atoms, such that they become ionized.
Answer:
Cutting, tearing, shattering, grinding, and mixing are further types of physical changes because they change the form but not the composition of a material. For example, mixing salt and pepper creates a new substance without changing the chemical makeup of either component.
