a solid → a liquid = melting (heat energy added) e.g. ice melts to water a liquid → a gas = vaporization (heat energy added) e.g. water to water vapour a solid → a gas = sublimation (heat energy added) e.g. dry ice (frozen CO2) to carbon dioxide a gas → a liquid = condensation (heat energy removed) e.g. cloud to rain a liquid → a solid = freezing (heat energy removed) e.g. water freezes to ice a gas → a solid = deposition (heat energy removed) e.g. water vapour to frost * solid-molecules tightly packed definite shape and volume(crystaline structure) * liquid-flow takes shape of container * gas-expands to fill container * plasma-electrons at 5000*C(neon lightning)
Physical changes are about energy and states of matter. Chemical changes happen on a molecular level.
Melting a sugar cube is a physical change because the substance is still sugar. Burning a sugar cube is a chemical change. The energy of the fire has broken down the chemical bonds.
the state of matter can change at different temperatura, for example when you put in the palm of your hand an ice cube until it makes wáter that is changing solid to liquid, another example is when the wáter of the ice cube you let it dry in the air that is changing liquid to gas.
There are actually at least 6 changes in states of matter: vaporization, condensation, melting, freezing, sublimation, and deposition.
Vaporization is when a liquid turns to a gas. There are 2 main types: evaporation and boiling. Boiling occurs when vaporization happens at a temperature above the boiling point of the substance; evaporization occurs at a temperature below the boiling point.
Condensation is when a gas turns to a liquid.
Melting is when a solid turns to a liquid.
Freezing is when a liquid turns to a solid.
Sublimation is when a solid turns directly into a gas without first changing into a liquid.
Deposition is when a gas turns directly into a solid without first changing into a liquid.
Do you mean state of matter or change or matter? :)
There are 3 'matters' gas, liquid and solid, everything is made up of these matters. Water is a liquid, cool it down (freeze it) and it is ice, a solid. Heat it back up and it's a liquid again if you heat the liquid up (boil it) steam or water vapour is given off, water vapour is the gas form of water.
Change in state are changes like from liquid to solid, from gas to liquid, or in rare cases from solid to gas.

Changes that are genetic
Matter changes state because of temperature and pressure. These quantities bring change.
Changes the temperature of the substance
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.
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
Changes of state of matter are physical processes, the molecule remain unchanged.
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
through changes of energy
They aren't; a change of state is a physical change
Physical Changes
no
Changes in the states of matter - or phase changes - do entail changes in volume.
Matter changes state because of pressure and temperature.
When water boils it changes from a liquid state to a gaseous state.
