When an object vibrates, it creates sound energy.  Sound energy travels in the form of sound waves. Sound waves are affected by many factors as they travel in various channels and media. SOLIDS LIQUIDS GASES TEMPERATURE  Form of kinetic energy TEMPERATURE Particles vibrate faster More collisions per unit time  0°C = 331 m/s 1°C increase = 0.60 m/s The warmer the temperature, the faster the speed of sound.  0.6 𝑚/𝑠 𝑣𝑠 = 331 m/s + (T) °𝐶 What is the speed of sound from a fire truck passing by the street in front of your house during summer with the temperature of 39°C? The atmospheric temperature in Baguio City is 20℃.
