Question

Statement 1: Cooled materials will contract, and heated materials will expand.

Statement 2: A measurement of this change in volume in relation to change in temperature is called the coefficient of thermal expansion.

A. Only Statement 1 is true.
B. Only Statement 2 is true.
C. Both statements are true.
D. Both statements are false.

Answer 1

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.
