Final answer:
The speed of sound at sea level at 70 degrees Fahrenheit is approximately 343 m/s, very close to the standard speed of sound in room temperature air (346 m/s).
Step-by-step explanation:
The speed of sound at sea level at 70 degrees Fahrenheit is approximately 343 meters per second (m/s). This measurement is close to the speed of sound in room temperature air, which is 346 m/s. The specific temperature of 70°F corresponds to about 21°C. Since the speed of sound is about 344 m/s at 21°C and sea level under normal atmospheric conditions, we can estimate the speed of sound at 70°F to be very similar.
It's important to note that the speed of sound varies with temperature because as air temperature increases, the air molecules move faster and transmit sound waves more quickly. Since 70°F is a commonly encountered temperature, it's reasonable to use the standard approximation provided for room temperature conditions.
