a solida liquid = melting (heat energy added) e.g. ice melts to water a liquida gas = vaporization (heat energy added) e.g. water to water vapour a solida gas = sublimation (heat energy added) e.g. dry ice (frozen CO2) to carbon dioxide a gasa liquid = condensation (heat energy removed) e.g. cloud to rain a liquida solid = freezing (heat energy removed) e.g. water freezes to ice a gasa 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.

When matter changes state does become a different kind of substance?

Changes of state of matter are physical processes, the molecule remain unchanged.


What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?

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.


What kind of changes in substances are always physical changes?

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.
