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

What is the term for a process that does not change the identity of a substance?
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.
What is a change that alters a substance without changing it into another substance?
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.
Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
What happens to substances or materials that undergo physical and chemical changes?
That depends on which change.Physical changes may result in a change in appearance, but never a change in composition. Ripping, folding, melting, boiling, dissolving, and crumpling are examples of physical changes. After all of these, the substance is still made of the same atoms/elements.A chemical change will change both the appearance and composition of the matter. Examples of this are burning and reacting with acid. After the change, the substance both looks different and has a different makeup.
Whats a physical change?
A physical change changes the property of a substance without changing the substance completely. In other words, a physical change is reversible.This change that occurs in the physical property/properties of a substance without altering its composition. A physical change:Possibly canchange withstate of matter (sublimation, decomposition, evaporation, melting, freezing, and condensation).No new material is formed.Possibly can dissolve.Possibly can occur either by increasing or decreasing the temperature.Is reversible.A physical change is any change not involving a change in the substance's chemical identity.a physical change is the color shape taste and smell of a substance.A physical change is where an object changes is size/ shape
Physical changes in a substance results in?
Physical changes in a substance result in
Physical changes in a substance result in what?
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.
What is the name of a change that does not result in a new substance?
These changes are of physical nature as boiling, freezing, sublimation.
When the physical form of substance changes without changing its composition?
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.

When two or more substance are combined so each substance can be separated by physical means the result is an?
The result is an MIXTURE
A change that does not result in new substance?
physical change
The process in which a rock changes as a result of heat generated from magma?
contact metamorphism
What physical changes occur to thermal conductivity?
because atoms expands when temperature increases in result physical changes.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
What happens to the identity of a substance when it makes a physical change?
there is to types of change to a substance chemical and physical in a physical change the result is a mixture also most times you can change your end result into what you started with e.g.freeze-melt evaporate-condesate
