The increase in volume of matter that occurs when matter is heated. a) Contraction b) Expansion c) kinetic energy d) Volume
katrin2010 [14]

Answer:

b) Expansion

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are; solid, liquid and gas.

A physical change can be defined as a type of change that involves an increase or decrease in the volume of a physical object (object). Also, this change can be reversed to the original state under certain conditions.

The increase in volume of matter that occurs when matter is heated causes an expansion.

This ultimately implies that, when a physical object (matter) is heated for a specific period of time, it result in an increase in the volume of the object; this phenomenon is generally referred to as expansion.

On the other hand, a decrease in volume of a physical object (matter) as a result of heat is known as contraction.
