The speed of sound is directly affected by the temperature of the medium. The hotter the medium the 1______ the sound travels. Heat, just like sound, is a form of kinetic energy. At higher temperatures, particles have 2______ energy (kinetic) and thus, vibrate 3_______ And when particles vibrate faster, there will be 4______ collisions per unit time. With more collisions per unit time, 5______ is transferred more efficiently resulting in sound traveling quickly. At oC, the speed of sound in air is 6______ m/s. The speed of sound is dependent on temperature of the medium where an increase is observed with an 7_______ in temperature. Specifically, the speed of sound increases by 8_______ m/s with every increase of 1.0°C On the other hand, when sound propagates in air where the temperature changes with altitude, sound bends towards the 9______ region. In this case, refraction happens. The refraction is due to the different refractive indices of air because of the difference in 10______.

Answer:
The speed of sound is directly affected by the temperature of the medium. The hotter the medium, the faster the sound travels. Heat, just like sound, is a form of kinetic energy. At higher temperatures, particles have more energy (kinetic) and thus vibrate faster. And when particles vibrate faster, there will be more collisions per unit time. With more collisions per unit time, energy is transferred more efficiently resulting in sound traveling quickly. At 0°C, the speed of sound in air is 331 m/s. The speed of sound is dependent on the temperature of the medium where an increase is observed with an increase in temperature. Specifically, the speed of sound increases by 0.6 m/s with every increase of 1.0°C. On the other hand, when sound propagates in air where the temperature changes with altitude, sound bends towards the colder region. In this case, refraction happens. The refraction is due to the different refractive indices of air because of the difference in temperature.
