What is the speed of sound in air if the temperature 40°C
Answer (1)
Answer:The speed of sound in air is influenced by temperature. At 20°C, the speed of sound in air is approximately 343 meters per second (m/s). The speed of sound increases with temperature. To estimate the speed of sound at 40°C, you can use the following approximation:\[ v \approx 331.3 + 0.6 \times T \]where \( v \) is the speed of sound in meters per second and \( T \) is the temperature in degrees Celsius.For \( T = 40 \)°C:\[ v \approx 331.3 + 0.6 \times 40 \]\[ v \approx 331.3 + 24 \]\[ v \approx 355.3 \text{ m/s} \]So, the speed of sound in air at 40°C is approximately 355.3 meters per second.
