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
