What is the speed of sound at an air temperature of 21 C?
344 m/s
At sea level, at a temperature of 21 degrees Celsius (70 degrees Fahrenheit) and under normal atmospheric conditions, the speed of sound is 344 m/s (1238 km/h or 770 mph).
What is the speed of sound in air when the temperature is 20 C 219 m/s 319 m/s 343 m/s 331 m s?
Answer: The speed of sound in air when the temperature is 20°C is 343 m/s. The speed of sound in air is 331 m/s at 0° C, 343 m/s at 20°C and 346 m/s at 25°C. Hence, the speed of sound in air when the temperature is 20°C is 343 m/s.
What is the speed of sound in air of temperature of 25 C?

What is the speed of sound in air if the temperature is 30 C?
350ms−1.
What is the temperature of air if the speed of sound?
In air, the speed of sound is related to air temperature T byv=331ms√TK273K=331ms√1+TC273°C.
What is the speed of sound in air if its temperature is 33 degrees Celsius *?
Approximate speed of sound
In a given ideal gas the speed of sound depends only on its temperature. Celsius is c = 331.3 m/s.
What is the speed of sound in dry air at 0 C?
approximately 344 m/sec
The speed of sound in dry air at a temperature of 0 degree C is approximately 344 m/sec (1130 ft/sec).
What is the speed of sound in air at 27 degrees Celsius?
340 m/s.
The velocity of sound at 27∘C is 340 m/s.
What is the temperature if the speed of sound is 346 m s?
25 degree Celsius
The speed of sound waves in air at 25 degree Celsius was computed in problem #66 to be 346 m/s.
Does sound travel faster through air 0 C or through seawater?
Sound Propagation in Sea Water
The speed of sound in sea water is, on average, about 1560 m/s, or 3490 mph. Compare this to the speed of sound in air, which is 343.2 m/s. The discrepancy is obvious: sound travels nearly five times faster in seawater than in dry air!
