Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
a. because the heat is transferred to the molecules and gives them more kinetic energy
b. because the warmer air allows the particles to be free from gravitational forces
c. because the heat liberates the potential energy inside each molecule eliminate
d. because the warmer air is less dense and particles can move more

Option (a) is the correct answer.

Explanation:

When temperature of surrounding atmosphere around the tire increases then it will lead to increase in the kinetic energy of molecules.

Due to increase in kinetic energy of molecules there will be more number of collisions between the air molecules that are present inside the bicycle tire.

Hence, it means heat has been transferred from the surrounding atmosphere to the molecules inside the tire.

Thus, we can conclude that the air molecules inside a bicycle tire speed up as the temperature gets warmer because the heat is transferred to the molecules and gives them more kinetic energy.
