Ain matter results in a change in its identity and properties.

a. chemical change
b. chemical property
c. physical property
d. physical change

the answer is A. Chemical change

Explanation:

if a chemical change happens it changes the properties and the identity of the material. e.g making a metal melt a higher melting point it is not a metal anymore it becomes a alloy because its properties have changed

A chemical change in matter results in a change in its identity and properties.

Option A

Explanation:

Every matter will undergo some kind of change when an external force or energy is acting on it. The changes exhibited by the matter is generally classified as physical change and chemical change. In physical change, there will not be any change in the identity of the matter neither there will be any change in the properties of the matter.

As the physical change does not affect the bonds of the matter, the identity, composition and properties of the matter will remain same, there will only be occurring deformation like cutting or shaping them, change in the state etc. But if the matter exhibits a change in its identity and properties that means the change affected the bonds of the matter.

And the bonds of the matter will get affected only by chemical change where the matters combine to form a different composition with different properties. So a chemical change in matter results in a change in its identity and properties.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
