Have You ever Wondered...

You are watching: How does temperature affect the speed of sound

exactly how do sound tide travel?How go temperature affect the speed of sound?What other factors impact the rate of sound?

Today’s Wonder that the job was inspired by JIHAI. JIHAI Wonders, “Why go the temperature impact the rate of sound?” thanks for WONDERing through us, JIHAI!

What’s today’s temperature where you live? The rising and also falling of temperature affects many parts the life. Heat days might welcome you exterior to play a video game with friends. Humid or merganser afternoons make this an ext difficult. Cold, snowy work can administer their very own sort of fun!

Did you recognize temperature have the right to even readjust the rate of sound? the true! space you wondering how? Let’s begin by talking about what sound is. Sound waves are made by vibrations. The waves can’t travel through a vacuum—they rely on the molecule of any type of given medium. These molecules lug sound tide from their resource to your ears!

What go temperature need to do with this? you may have learned a bit about this subject in school. Warm is a type of energy—the much faster a medium’s molecule move, the higher its temperature is. As soon as these molecules move slower, the temperature cools.

Look around you. Whatever you see is make from molecules: computer system screens, house plants, piece of paper, and also even your very own body! The wait you’re breathing also contains molecules. The temperature exterior on any type of given work is figured out by the rate of wait molecules.

On warm days, wait molecules relocate faster. That way they likewise carry sound waves faster, increasing the rate of sounds. Can you guess what happens on the coldest winter days? If girlfriend think sound travels slower, you’re right! wait molecules relocate at a slower pace when the temperature is cold, therefore they lug sound tide at a slower pace as well.

Of course, speed isn’t everything. Have you ever noticed that you’re able to hear sound from farther away on cold days? it’s not just your imagination! when sound moves much faster in warm air, the doesn’t take trip as far as that does in chillier temperatures.

Temperature no the only thing that affects the speed of sound. Because that instance, humidity additionally has an impact. By do air much less dense, low humidity helps sound waves move faster. Air pressure can additionally make a difference.

The following time you’re in search of a funny outdoor activity, try experimenting v sound. Keep in mind the wait temperature, and also then invite part friends to assist you see exactly how far and fast various sounds have the right to carry. Have fun learning much more about exactly how sound tide travel!
