Please say yes or no and explain why.​

Answer 1

Answer: If matter goes through a chemical change then the physical properties are not likely to stay the same.

Step-by-step explanation:

When chemical composition of a substance changes during a chemical reaction then it is called a chemical change.

Chemical change always leads to the formation of new substances. Properties like chemical reactivity, combustion, rusting etc are chemical changes.

For example,
`N_(2) + 3H_(2) \rightarrow 2NH_(3)`

Here,
`NH_(3)` will have different chemical as well as physical properties as compared to
`N_(2)` and
`H_(2)`.

As physical properties are the properties that cause change in state of a substance.

Properties like boiling point, state of substance etc are physical properties.

Thus, we can conclude that if matter goes through a chemical change then the physical properties are not likely to stay the same.
