"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
Mass and chemical composition
Pressure and temperature are two factors that both affect the state of any type of matter.
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance
A chaqnge of the state of matter is allways a physical change.
covalent bonds
1) melting-solid state changes into liquid state and 2)freezing-liquid state changes into solid state
Matter changes state because of pressure and temperature.
how temperature can bring about changes in the state of matter
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
Mass and chemical composition
Pressure and temperature are two factors that both affect the state of any type of matter.
Changes of pressure or temperature
Matter changes state because of temperature and pressure. These quantities bring change.
Changes of state of matter are physical processes, the molecule remain unchanged.
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.
