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.

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).
A change that alters the substance but does not change the substance is?
A physical change.Changes between Solid, Liquid, and Gas.
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.
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.
Is mashing a banana a chemical change or physical change?
This is a physical change, because you are only changing the physical appearance, not the substance's chemical properties.
Any change that alters a substance without changing it into another substance is a?
a physical change

What alters a substance into another?
Heat can alter a substance into another substance. Such as when you bake a cake the batter is changed into a cake and can not be changed back.

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.
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.
What is the substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
What is a substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
Is ripping physical or a chemical change?
Ripping is a physical change because it alters the form or appearance of a material without changing its chemical composition. When a substance is ripped, its size and shape may change, but the molecular structure remains intact. Therefore, ripping does not produce a new substance, which is a key characteristic of chemical changes.
Is heat changing water to steam a chemical or physical change?
The process of heat changing water to steam is a physical change. During this transformation, water molecules gain energy and move from a liquid state to a gaseous state, but their chemical composition remains the same (H₂O). In a physical change, the substance alters its form or state without changing its chemical identity.
17 Explain how color can be classified as both a physical property and as one indication of a chemical change?
Color can be classified as a physical property because it can be observed without changing the chemical composition of a substance. However, color change can also indicate a chemical change when it is a result of a reaction that alters the molecular structure of the substance, leading to a new chemical identity. In this case, the color change is a visual representation of the chemical transformation that has occurred.
