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.
chemical change
changes of state are called phase changes.
No, substances do not change states at the same temperatures. Each substance has its own unique melting and boiling points, which depend on its molecular structure and intermolecular forces. For example, water freezes at 0°C and boils at 100°C, while other substances like ethanol and mercury have different freezing and boiling points. Thus, state changes occur at specific temperatures for each material.
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.
The following will change state from solid to liquid.
Actually no, the only thing that changes is the density. The mass doesn't change when it's changing states.
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
