TRUE or FALSE
1. Temperature is affected by the movement of particles in the environment.
2. If the molecules vibrate faster the speed of sound in a medium becomes greater.
3. When the temperature increases, the air molecules move faster so the speed of sound is slower.
4. Solid, liquid, and gas are the medium in propagating sound.
5. The factors affecting the speed of sound are density and humidity only.
