Matter does not move from a solid, to a liquid, to a gas. It is more proper to say that it changes its state. At different temperatures, all matter changes its state because of the different levels of energy that are required for it to maintain certain states. At the lowest temperatures, matter is a solid. As the temperature is increased, it can change into a liquid, and ultimately a gas. There are even higher states like plasma that involves even higher temperatures, like those found in the sun.
change of state is when the different states of matter are changed into one another. states of matter are gas, liquid, plasma and solid.
The variables that influence a state of matter include temperature and pressure. At higher temperatures, matter tends to exist in a gaseous state, while at lower temperatures, it may be solid or liquid. Increasing pressure can also cause substances to change states, such as from a gas to a liquid.
plasma
there are no states of matter in helium.helium is a gas,wich is a state of matter.
chemical change
There are many different states of matter, however the three most commonly known are: solid, liquid and gas. There is also a fourth that is widely used, plasma, however there is some debate as to whether or not it should be separated from the gas state. While the states themselves are unchanging, matter can change between the states. For instance, in different temperatures, water changes from a liquid to a solid (freezing) or from a liquid to a gas (evaporation) and vice-versa. Some substances, such as dry-ice (CO2), change directly from a solid to a gas (sublimation). There are other states of matter which are less known, and generally only used in specific sciences.
Physical change
Yes, matter can change states after a physical change. Physical changes involve changes in the arrangement of particles without altering the chemical composition. For example, melting ice (solid to liquid) and boiling water (liquid to gas) are physical changes that involve changes in state.
