There are not two changes in mattter - six examples are shown below
Gas to liquid e.g. steam to water (condensation)
Liquid to solid e.g. water to ice (freezing)
Solid to liquid e.g. ice to water (melting)
Liquid to gas e.g. water into steam (evaporation/vaporization)
Solid to gas/vapor and the reverse e.g. solid iodine become vapor (sublimation)
The study of properties of matter and how it changes is called chemistry.
Chemistry - the study of the properties of matter and how matter changes
laws and principle governing changes of matter
Matter changes state because of pressure and temperature.
nothings its a dumb question
chemistry
how temperature can bring about changes in the state of matter
There are 2 kinds of changes,they are physical and chemical changes.Physical Change-is a change in the form of matter but in it's identity.Chemical Change-is a change in which one kind of matter is changed in to a different type of matter.
Matter is modified by phases changes.
Matter can change through physical changes, such as melting or boiling, which alter its form but not its chemical composition. Matter can also undergo chemical changes, where its chemical composition is altered through chemical reactions like rusting or burning.
the materials changes in matter example ,candle ,paper ,sugar and many more
it causes the 1. melting of solid substances 2. the solidification of liquid substances\ 3. the deformation of matter.
