There are 400 air particles in a tyre. Tobby pumps more air into the tyre. What will happen to the air pressure in the tyre?
The pressure will decrease because the number of air particles have increased.
The pressure will increase because the number of air particles have decreased.
The pressure will decrease because the number of air particles have decreased.
The pressure will increase because the number of air particles have increased.

Why does oil float on top of water?
Because their densities are the same.
Because water is less dense than oil
Because oil is less dense than water
There are air particles in containers A and B. In which container is the pressure higher and why?
The pressure in container B is higher because it has more air particles.
The pressure in container B is higher because the air particles have less volume.
The pressure in container A is higher because the air particles have more volume.
The pressure in container A is higher because it has more air particles.
