Fig. 1.1 shows a toy water rocket.
The rocket is half-filled with water and connected by rubber tubing to a pump.
Air is then pumped into the rocket so that the pressure of the air inside the rocket increases.
Explain, in terms of particles, why the air in the rocket exerts a pressure on the walls of the rocket.
The temperature of the air in the rocket remains constant as air is pumped into the rocket.
Explain why increasing the number of air particles in the rocket increases the pressure of the air in the rocket.
When the air pressure in the rocket is high, the rubber tubing is removed from the rocket.
The water in the rocket is expelled downwards.
Explain, in terms of momentum, why the rocket begins to accelerate upwards.
As the water is expelled from the rocket, the upward acceleration of the rocket changes.
Suggest two reasons for the change in the acceleration of the rocket.
