The Magic of Bicycle Tire Temperature Increase

How does the increase in temperature affect the size of the bicycle tire?

Does the tire shrink or expand when the air inside heats up?

A. The tire shrinks because the mass of air inside the tire decreases.

B. The tire expands because the mass of air inside the tire increases.

C. The tire shrinks because the volume of air inside the tire decreases.

D. The tire expands because the volume of air inside the tire increases.

Final answer:

When the air inside a bicycle tire heats up, the tire expands due to the increase in volume of the heated air.

Explanation:

Imagine the thrill of riding your bicycle on a bright sunny day, feeling the wind in your hair and the sun on your face. As you pedal faster and faster, the air inside your bicycle tire also starts to heat up. But what happens to the tire when this magical heating process occurs?

Well, according to the gas law known as Gay-Lussac's Law, when the temperature of a gas increases, its volume also increases, as long as the pressure remains constant. In the case of a bicycle tire, the pressure inside remains relatively constant, so the tire expands as the volume of the heated air increases.

So, the next time you hit the road with your trusty bicycle, remember that the increase in temperature actually works its magic on your tire by making it expand and ride smoothly on the warm pavement!
