As thermal energy increases or decreases, a substance will change state. This relates to temperature in that the higher the temperature of something, the greater its thermal energy.
A change in state can be caused by either adding or removing energy from a substance. For example, adding heat can cause a solid to melt into a liquid, and removing heat can cause a liquid to freeze into a solid. Pressure changes can also cause a substance to change state, such as turning a gas into a liquid by increasing pressure.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
Yes, that is correct. A physical change is a change in a substance that does not involve changing its chemical composition. This can include changes in size, shape, or state of matter without altering the substance's fundamental makeup.
You can change the state of matter of a substance by applying heat to it. When you heat a solid, it melts into a liquid. When you heat a liquid, it evaporates into a gas. This process is known as melting and boiling.

a physical change ex. change in state
A chemical change in matter produces a new substance. A physical change, on the other hand, only alters the state or phase of matter without producing a new substance.
Any change to the state of matter of a substance is physical.
