States of matter are generally described as solid, liquid and gas (although there are more to think about when you really get into science). As such a change in matter is seen to be a change in state; from solid to liquid (melting), from liquid to gas (boiling), from solid to gas (sublimation), from gas to liquid (condensation) and liquid to solid (freezing).
Interestingly each chemical has a unique melting/freezing point and boiling/condensation point. We can use those temperatures to help us identify unknown substances.
With the help of some physical and chemical processes matter changes its state. Like using heating , cooling etc we can change the state of matter,
Matter affects us in that we are created out of matter and everything we touch is also made of matter. Matter is everywhere in the universe and everything we use is made from some type of matter.
Changes in the states of matter occur through processes like melting, freezing, condensation, vaporization, and sublimation. These changes involve the rearrangement of particles at the molecular level due to changes in temperature or pressure. During these transitions, energy is either absorbed or released.
Forms of energy related to changes in matter may include kinetic, potential, chemical, electromagnetic, electrical, and thermal energy.
The study of properties of matter and how it changes is called chemistry.
Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.

Chemical changes in matter have the most potential danger and damage. A chemical change is a change in which one kind of matter is changed into a different type of matter. Some examples of chemical changes: the rusting of your car, setting your shoe on fire, digesting food, and the burning of magnesium metal in oxygen to form magnesium oxide.
