Solid to liquid is melting
Liquid to Gas is evaporation
Solid to gas is sublimination
Liquid to solid is freezing
Gas to liquid is condensing
Changes in the states of matter - or phase changes - do entail changes in volume.
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
Matter changes state because of pressure and temperature.
Heat change and pressure change are the only reasons, but in our atmosphere, more often heat.
how temperature can bring about changes in the state of matter
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
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
Matter changes state because of temperature and pressure. These quantities bring change.
"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.
