1. Effect of Temperature on the Speed of Sound

2. Temperature is the average kinetic energy of a substance. It is the hotness or coldness of an object. It can be measured by a thermometer. Temperature

3. There are three major temperature scales. They can be converted through from one another using the following equations: Temperature Scales

4. The speed of sound in air is dependent on the air temperature. Sound travels faster in hot air compared to cold air. At high temperatures, particles of air vibrate faster. Hence, it allows sound waves to travel faster. Temperature and Sound

5. Sound travels at a speed of 331.0 m/s in dry air at 0ºC. For every increase of 1ºC in air temperature, sound travels faster by 0.6 m/s .

6. The temperature is always expressed in Celsius. Temperature and Sound

7. On the Celsius scale, the standard room temperature is 20˚C. Calculate the speed of sound at standard room temperature.

8. Step 1 : Identify what is required to find in the problem. We are required to find for the speed of sound On the Celsius scale, the standard room temperature is 20˚C. Calculate the speed of sound at standard room temperature.

9. Step 2 : Identify the given in the problem. On the Celsius scale, the standard room temperature is 20˚C. Calculate the speed of sound at standard room temperature.

10. Step 3 : Write the working equation Step 4: Substitute the given values. On the Celsius scale, the standard room temperature is 20˚C. Calculate the speed of sound at standard room temperature.

11. Step 5: Find the answer On the Celsius scale, the standard room temperature is 20˚C. Calculate the speed of sound at standard room temperature.

12. The measured temperature in a large open air venue is 97ºF. Find the speed of sound in this venue in km/h.

13. Step 1 : Identify what is required to find in the problem. We are required to find for the speed of sound The measured temperature in a large open air venue is 97ºF. Find the speed of sound in this venue in km/h.

14. Step 2 : Identify the given in the problem. The measured temperature in a large open air venue is 97ºF. Find the speed of sound in this venue in km/h.

15. Step 3 : Write the working equation The measured temperature in a large open air venue is 97 F. Find the speed of sound in this venue in km/h.

16. Step 4 : Since the given temperature is in o F, convert it to o C. The measured temperature in a large open air venue is 97ºF. Find the speed of sound in this venue in km/h.

17. Step 5 : Substitute the given values Step 6: Find the answer The measured temperature in a large open air venue is 97 F. Find the speed of sound in this venue in km/h.

18. The speed of sound in air is dependent on the temperature. The higher the temperature, the faster the speed of sound. The speed of sound in dry air at 0ºC is equivalent at 331 m/s. 1 2 Always convert the temperature into celsius in getting the speed of sound. 3

19. The speed of sound in dry air is 450.0 m/s. Sound travel faster in cold air than in warm air. The speed of sound in air is dependent on temperature. Air molecules vibrate slower at high temperature causing sound waves to travel faster. To slow down the speed of sound, air temperature must be increased. Write T if the given statement is true and if false, underline the incorrect word/s and write the corresponding correct word/s for it.

20. Why almost all concerts in an open air venue are being held at night?
