Temperature in °C
1. Based on the graph, what is the relationship of temperature to the speed of
sound in air
2. From your graph, find the interval where the speed of sound at 15°C is located.
3. Extend the line of your graph and find the interval where the speed of sound at
25°C is located.
4. Use your graph to determine how much does the speed of sound change for the
given change in temperature.​
