Answer (1)
Answer:1. Based on the graph, what is the relationship of temperature to the speed of sound in air? The relationship between temperature and the speed of sound in air is directly proportional. This means that as the temperature increases, the speed of sound also increases.2. From your graph, find the interval where the speed of sound at 15°C is located. - The speed of sound at 15°C is located between 340 m/s and 341 m/s. 3. Extend the line of your graph and find the interval where the speed of sound at 25°C is located. - Extending the line, the speed of sound at 25°C is located between 346 m/s and 347 m/s. 4. Use your graph to determine how much does the speed of sound change for a given change in temperature. - We can see that for every 5°C increase in temperature, the speed of sound increases by about 3 m/s#KEEPONLEARNING
