when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
Changes in the states of matter - or phase changes - do entail changes in volume.
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,
no
For example melting and evaporation.
Changes of state of matter are physical processes, the molecule remain unchanged.
Matter changes state because of pressure and temperature.
how temperature can bring about changes in the state of matter

Chemistry
my dick is what happens
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
Some laws involved in changes of matter are the Law of Conservation of Matter and the Law of Conservation of Energy. Changes in matter include physical and chemical changes.
