Is a change that alters the form of a substance without changing it into another substance is called what?
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
What represents a physical change apex?
A physical change is a type of change that alters the form or appearance of a substance without changing its chemical composition. Examples include melting, freezing, boiling, and cutting.
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.
Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No, that statement is incorrect. A physical change does not involve changing the composition of a substance or forming new substances. It only alters the physical state or appearance of a substance without changing its chemical composition. When a substance changes composition and forms new substances, it is considered a chemical change.
Is it true a physical change never alters the form or appearance of a substance?
No, a physical change can alter the form or appearance of a substance without changing its chemical composition. For example, melting ice changes its form from solid to liquid without altering its chemical composition.
Any change that alters a substance without changing it into another substance is a?
a physical change

What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
Chemicel and physical change of matter?
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.
When a change in matter alters the basic nature of a substanc it is called what?
When a change in matter alters the basic nature of a substance, it is called a chemical change. In a chemical change, the substances involved react to form new substances with different properties than the original ones.
What is the driving force of phase change?
The driving force of a phase change is a change in the energy state of the substance. This can be caused by a change in temperature or pressure, which alters the balance of forces between the particles in the substance, leading to a transition to a different phase.
What is the substance that alters the speed of chemical action?
catalyst
What a pollutants?
A pollutant is a substance that alters the composition of its surroundings.
The tarnishing of metal is an example of a?
chemical change where the metal's surface reacts with oxygen and other compounds in the environment, forming a new substance that alters the metal's appearance.
Why is change of color a physical change?
Because a physical change just alters the appearance of an object, where as a chemical change alters the texture or state of an object.
How does the depletion of the ozone layer contribute to climate change?
Depletion of ozone alters ecosystem. This then alters the climate change.
In a physical change a substance changes its but not its identity?
In a physical change, the substance undergoes a change in its appearance, form, or state of matter without altering its chemical composition. This means that the molecules in the substance remain the same before and after the change. Examples of physical changes include melting, freezing, boiling, and dissolving.
