Answer

Brief Explanations:

When the temperature of a medium increases, the kinetic energy of its particles increases. Faster - moving particles bump into each other more often, which allows sound waves (which are mechanical waves that rely on particle - to - particle interactions for propagation) to travel more quickly.

Answer:

increases because the particles bump into each other more often.
