Question 52 • EA Academy Civics 9

Which factors affect the speed of sound?

Answer
A
type and volume of medium
B
temperature and type of medium
C
volume and temperature of medium

Explanation

The speed of sound depends on the properties of the medium it travels through and, in many media, the medium’s temperature. For example, sound travels at different speeds in air, water, and solids, and its speed in air increases as temperature rises. The volume of the medium does not determine the speed, so the correct choice is “temperature and type of medium.”
