We know that sound does not travel in outer space because the vacuum environment has no particles to carry the sound wave. This is because sound travels by particles bumping into each other as they vibrate. Therefore, sound can travel through solid, liquid, and gas. Sound waves travel four times faster in water than in the air due to the distance between particles. In a liquid state, the particles are nearer to each other compared to a gaseous state and when a particle receives some energy from the sound wave, it will then transfer it to the neighbouring particle and causes vibrations. Another interesting fact is that temperature also influences the speed of sound. However, it is not due to how closely the particles are to each other but due to the amount of energy that each particle carries. Hot or warm particles carry more energy and transmit sound better compared to colder particles. Water in tropical areas transmits sounds faster compared to water in Antarctica.
