Here you've got them all six in a row:
and all the reverse changes:
The state of matter can be changed by altering the temperature or pressure of a substance. For example, increasing the temperature of a solid can cause it to melt and change into a liquid, while lowering the temperature of a gas can cause it to condense into a liquid. Similarly, changing the pressure can also affect the state of matter.
Oxygen is an example of one of the four phases of matter, it being of a gaseous phase. Phase is simply another term for 'state.' Liquid, Solid and Plasma being the others.
Phase change
An example of cooling matter changing its state is when water vapor condenses into liquid water at lower temperatures, such as when steam from a kettle turns back into water droplets on a cold surface.
When thermal energy is added to matter, the particles within the matter begin to vibrate and move faster. This increase in movement causes the matter to expand, changing its physical state from solid to liquid, and then to gas at higher temperatures.
The characteristic obtained by changing the state of matter, such as the ability to melt, is called a physical property. Physical properties describe the state of a substance without changing its chemical composition. In the case of melting, the physical property is the temperature at which a solid turns into a liquid.
The characteristic of matter you are referring to is called a physical property. The ability to melt is an example of a physical property exhibited by ice, where it changes from a solid state to a liquid state when heated.
In science, another word for state may be phase. For instance a state of matter is also called a phase of matter.
State? Or phase? It would be a liquid phase. But its state is unknown since the state of a substance includes its pressure, temperature AND phase. Phase is a part of a state, but a state is not a phase.
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
state or phase
Yes, because it's changing the state of matter from a solid, to either gas or liquid.
