Question

Which of the following changes can alter the form of a substance but does not necessarily change it to an other substance?

Answer 1

Answer:

• The physical changes can alter the form of a substance but does not necessarily change it to an other substance

Explanation:

• The physical properties of matter is one that does not depend on composition.It just change the form of matter into another form with changing into composition.

• Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

• The three states of matter are: solid, liquid, and gas. The melting point and boiling point are related to changes of the state of matter. All matter may exist in any of three physical states of matter.

Example:

1. When water is boiled then it change into vapors. Now the form of water is change but its composition is same like water
2. When water freezes into ice, now phase are different i.e water is liquid while ice is solid but both have same composition.
