Glycerine
Answer is Right!
Answer is Wrong!
The speed of sound is the distance that a sound wave travels in a given amount of time. It is measured in meters per second (m/s). The speed of sound depends on the medium through which it is traveling. Sound travels fastest in solids, followed by liquids, and slowest in gases.
The speed of sound in water is about 1,500 m/s. The speed of sound in air is about 343 m/s. The speed of sound in glass is about 5,000
m/s. The speed of sound in glycerine is about 1,200 m/s.Therefore, the speed of sound is greatest in water.
- Sound travels faster in solids than in liquids because the molecules in a solid are closer together than the molecules in a liquid. This means that the sound waves can travel from one molecule to the next more easily in a solid than in a liquid.
- Sound travels faster in liquids than in gases because the molecules in a liquid are closer together than the molecules in a gas. This means that the sound waves can travel from one molecule to the next more easily in a liquid than in a gas.
- Sound travels slowest in gases because the molecules in a gas are far apart from each other. This means that the sound waves have to travel a longer distance between each molecule, which makes them travel slower.
