How Does Temperature Effect Speed Of Sound?

Temperature is a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.

What is the effect of temperature on speed of sound?
Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square  wiki.answers.com
How the Speed of Sound Changes with Temperature
Sound travels faster at higher temperatures. The formula for figuring out the speed of sound is v = 331 m/s + 0.6m/s/degree where v is velocity, m is meters, s is seconds and degree is degrees Celsius. This formula is accurate at typical humidity.  www.ehow.com
The temperature of the room has an effect on the speed of sound. Why is this?
hot air has more kinetic energy. more kinetic energy means more velocity, so when velocity of air is more so its vibration will be faster so increasing its frequency so its speed will increase.  answers.yahoo.com
