Answer:

329 m/s

358 m/s

yes

Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly

1. the speed sound in dry air at a temperature of 0 degree C is approximately 344 m /sec

2.331 m/s +(0.6m/s C)T

331 m/s + (0.6m/s)c 45C

331 m/s +27

358 m/s

3. the temperature is warmer sound travel fast but if the temperature is colder sounds travel slower.

4. temperature is another condition that effect the speed and sound,heat ,like sound is a form of kenetic energy the speed sound is also affected by the other factors such as humidity and air pressure.
