How do you find speed of sound with temperature?
If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = ??RTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=??RTM=??RTM(273K273K)=?(273K)?RM?T273K?331m/s?T273K. v=f?.
What is the speed of sound at 37 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 at 0 degrees Celsius?
approximately 344 m/sec
The speed of sound varies depending on the type of elastic medium it is propogated in. The speed of sound in dry air at a temperature of 0 degree C is approximately 344 m/sec (1130 ft/sec).
What’s the speed of sound in air?
If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second.
What is the speed of sound in air?
344 m/s
The term is commonly used to refer specifically to the speed of sound in air. 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 it speed of sound in air?
761.2 mph
The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) is 761.2 mph (1,225 km/h).
How fast does sound travel if the air temperature is 20 C?
about 343 metres per second
At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.9 s or one mile in 4.7 s.
At what temperature will the speed of sound in air be 349 m s?
30 degrees Celsius
At 30 degrees Celsius, the speed of sound is 349 m/s.
Is a temperature of 29 normal?
Body temperature below 95°F (35°C) is considered abnormally low, and the condition is known as hypothermia. This happens when your body loses heat faster than it can produce heat. Hypothermia is a medical emergency, which if left untreated can lead to brain damage and cardiac failure.
How is the speed of sound in air affected by the temperature of air?
Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. The speed of sound at room temperature air is 346 meters per second.
What is the speed of sound in air when the air temperature is 303 K?
Convert the temperature into kelvin and then enter the temperature into the equation vw=(331m/s)?303K273K=348.7m/s.
What is the speed of sound in air at 22 C?
The speed of sound in dry air at 22 °C is 344.632 m/s.
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 speed of sound in the air if the temperature is 35 C?
The speed of the sound at this temperature is 352 m/s.
What is the speed of sound in air when the temperature is 32 C?
1085.1 feet per second
For example, at zero degrees Celsius (32 degrees Fahrenheit), the speed of sound is calculated to be 1085.1 feet per second.
What is the speed of sound at the lowest temperature?
In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second. The speed of sound in liquid water at 8 °C (46 °F) is about 1,439 metres (4,721 feet) per second.
How do you calculate the speed of sound in a gas?
Solution: The speed of sound in a gas is given by v=??RT/M.
