Does not change a substances identity physical or chemical change?
A physical change does not alter a substance's chemical composition; it only affects its physical properties like shape, size, or state of matter. Examples include melting, freezing, or boiling.
What are two physical properties that can vary even when the substance with these properties does not change?
Density and temperature can both vary for a substance without changing the identity of the substance. The density of a substance can change with temperature, pressure, or the presence of impurities, while the temperature of a substance can change due to external factors like heating or cooling.
What happens to energy during a change of state Why is it physical change?
During a change of state, energy is either absorbed or released as heat. This is because the particles in a substance need energy to break their bonds and move into a new arrangement. A change of state is a physical change because it does not involve a change in the chemical composition of the substance, only its physical properties.
Is Gatorade a physical change?
No, Gatorade is not a physical change. It is a liquid beverage composed of water, sugars, and electrolytes. Mixing these ingredients together does not alter their chemical composition, so it does not involve a chemical reaction or change in the substance's identity.
What happens to matter and the particles of an object during physical change?
During a physical change, the matter remains the same, but the arrangement and position of the particles within the object may change. This can involve processes like melting, freezing, or evaporating, where the particles gain or lose energy to shift from one state to another while still maintaining their identity.

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.
A physical property of a substance can only be observed if the substance changes into a different substance?
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
What is the diffeference between a physical and a chemical change?
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
What kind of change happens when the composition of a substance does not change?
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
In a physical change a substance changes its but not its identity.?
Appearance
When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
A change that affects the physical properties but not the identity of a substance is?
chemical change
Physical Change?
Changes of the matter that do not change the composition of the substance.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
What is A change in the matter that does not change its identity?
A physical change does not change the identity of matter.
What happens when you take the heat away from a substance?
Physical change
