Question
- A student measures the air pressure inside her bicycle tires before and after she goes on a long bike ride. What will she most likely observe.1 pointThe pressure in both tires is lower after the ride.The pressure in both tires is higher after the ride.The pressure in the front tire is higher after the ride, and the pressure in the back tire is lower after the ride.The pressure in the back tire is higher after the ride, and the pressure in the front tire is lower after the ride.
Solution
The student will most likely observe that the pressure in both tires is lower after the ride. This is because as the tires are used during the ride, the air inside them heats up and expands, causing some of it to escape and thus lowering the pressure.
