What kind of change occurs when ice becomes liquid water?

a. substance change

b. physical change

c. melting reaction

d. chemical change

The correct answer is -

B.physical change.

Explanation:

Melting of ice is considered as a physical change because during this process, only the physical state of water is changed from solid state (that is ice) to liquid state, which is water.

There is no formation of any new chemical substance and moreover, this change can also be reversed by freezing (giving zero degree temperature to water).

Thus, option b) is the right answer.

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
