When a cold tyre is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the
air molecules hit the walls of the tire less frequently
rubber in the tires reacts with oxygen in the atmosphere
air molecules speed up and collide with the tire walls more often
air molecules diffuse rapidly through the walls of the tire.
Gas pressure is caused by
Molecules colliding with each other
Molecules condensing to a liquid
Molecules colliding with the walls of containers
Barometers
When you push down on a bike tyre, you feel resistance because
The kinetic energy of the particles increases so the temperature increases
The kinetic energy of the particles increases so the pressure increases
The volume has increased so the pressure increases
The volume has decreased so the pressure increases
At 20oC, the same volume of helium and hydrogen gas will have
the same average kinetic energy
the same kinetic energy for all particles
different kinetic energy as they weigh different amounts
different kinetic energy as the particles are different sizes
According to the kinetic theory of gases, gas particles
Do not always move in straight lines
Have most their volume occupied by empty space

False
Energy is lost when particles collide with each other or the walls of the container
