The substance could liquefy or solidify.
Cooling a gas: change from the gas phase to the liquid phase
Cooling a liquid: change from the liquid phase to the solid phase
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
Viscosity is a physical property of a substance, which describes its resistance to flow or deformation. It is determined by the intermolecular forces within the substance and is not a result of any chemical changes or reactions.

When a substance is heated, it may undergo physical or chemical changes such as melting, evaporation, sublimation, or decomposition. These changes can result in alterations in the substance's physical state, color, texture, or chemical composition.

Cooling a hot substance may result in the molecules slowing down, leading to a decrease in volume and contraction of the substance. Additionally, cooling can cause a phase change, such as from a liquid to a solid, as the substance reaches its freezing point.

One possibility is a change in state.
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
These changes are of physical nature as boiling, freezing, sublimation.
This process is known as a physical change. It involves a change in the state or appearance of a substance but does not result in the formation of a new substance. Examples of physical changes include melting ice, boiling water, and breaking a glass bottle. The chemical composition of the substance remains the same throughout the physical change.

A physical change, such as melting ice or cutting paper, does not result in a new substance being formed. These changes only affect the physical state of the matter, not its chemical composition.
Physical changeschemical changesYou must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
