Final answer:

Both cooled materials contracting and heated materials expanding, and the measurement of this change in volume is called the coefficient of thermal expansion, are true statements.

Step-by-step explanation:

Both statements are true. Cooled materials contract, while heated materials expand. This is known as thermal expansion. The change in volume of a material in relation to the change in temperature is measured using a coefficient of thermal expansion. This coefficient quantifies the extent to which a material expands or contracts with temperature changes.
