The same way a chemical rocket works. Instead of burning fuel to create a force to propel the rocket, stored pressure released in one direction propels the rocket.
Both chemical and pressure rockets make use of Newton's Third Law of Motion, for every action there is an equal and opposite reaction.

A pressure rocket works by building up pressure within a sealed chamber, typically by introducing compressed air or another gas. Once the pressure reaches a critical point, it is released through a nozzle, creating thrust that propels the rocket in the opposite direction. This is based on Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.

What is a rocket toy name?
A popular rocket toy name is the "Stomp Rocket." It is a toy rocket launcher that uses air pressure to propel foam rockets into the air when stomped on.
Does water temperature affect how fast the rocket launches?
Yes, water temperature can affect how fast a rocket launches. Warmer water will create more steam and pressure, potentially causing the rocket to launch faster compared to colder water. However, other factors such as the design of the rocket and the amount of pressure built up also play a significant role in determining the launch speed.
What can you increase rocket stability?
You can increase rocket stability by using fins to create aerodynamic forces that keep the rocket pointing in the right direction, ensuring the center of mass is located in front of the center of pressure, and using a gimbaled engine or thrust vectoring to control the rocket's direction.
What happens if your water rocket leaks?
If your water rocket leaks, it will not be able to build up enough pressure to launch properly. This could result in a failed launch or a weak trajectory. It is important to ensure that your water rocket is properly sealed before each launch to achieve the best performance.
How a rocket launches off the ground by using Newton's law of motion?
The third law applies here. For every action there is an equal and opposite reaction. When the rocket fuel is ignited it exerts enormous thrust directed downwards. If the rocket is not constrained to the launching pad (with very very heavy restraints) it sees no other way to nullify the enormous thrust but to set itself in motion. Soon as more fuel burns, the rocket accelerates. As a side, if the rocket was restrained with very heavy agents, these agents (in the form of nuts and bolts or whatever) will have to bear the thrust of the rocket engine. For the non-scientist: Consider a balloon with large pressure inside relative to small pressure outside. It doesn't move up, because there is an equal force down (inside). It doesn't move right, because there is an equal force on the left side (on the inside of the balloon). If you put a hole in the balloon (the inside gas rushes out due to the difference in pressure) there is an unbalance of forces. On one side, there is internal pressure, but on the other side there is a hole (around no pressure). So the balloon moves to the opposite side of the hole. Rockets work the same way (more or less).
How much pressure did the Saturn V rocket exert?
5 Million Newtons was the pressure exerted by Saturn v rocket
What energy does a rocket work on?
A rocket works on chemical energy stored within its propellants. This energy is released through a controlled combustion process, creating high-pressure gases that are ejected to produce thrust.
How is a real rocket able to blast into space?
A real rocket is able to blast into space by relying on powerful engines that burn fuel to generate thrust. The force of this thrust pushes the rocket against the force of gravity, allowing it to break free from Earth's gravitational pull and ascend into space. Rockets also have carefully calculated trajectories and guidance systems to navigate through different stages of their journey into space.
How much pressure is needed for a bottle rocket?
The pressure needed for a bottle rocket varies depending on the design and size of the rocket. Generally, pressures ranging from 30-60 psi are sufficient for launching a bottle rocket effectively. However, it is important to carefully follow the instructions provided with the rocket kit to determine the specific pressure required for optimal performance.
What effect does pressure have on a bottle rocket?
it pushes the rocket into the air to make it go higher.
How much pressure goes in the water rocket?
The pressure in a water rocket can range from 30 psi to over 100 psi, depending on the design and materials used. This pressure builds up inside the rocket as air is pumped into the chamber before launch.
Why center of pressure is below center of gravity?
I assume you are talking about a model rocket. Center of pressure needs to be below center of gravity in order for the rocket to fly straight. Mathematically, the rocket will tilt around the center of gravity but appear to be pushed from the center of pressure, hence the need for the center of pressure to be below the center of gravity, otherwise the rocket will just corkscrew off the pad. The fins move the center of pressure down.
What is a rocket toy name?
A popular rocket toy name is the "Stomp Rocket." It is a toy rocket launcher that uses air pressure to propel foam rockets into the air when stomped on.
What determines how much thrust is generated in a solid fuel rocket engine at any given time?
The amount of exposed surface area of the fuel
How do center of mass and center of pressure affect a rocket?
The center of mass is the average position of the mass of the rocket, affecting stability and control, while the center of pressure is the average location where aerodynamic forces act, influencing the aerodynamic behavior of the rocket. The relative positions of the center of mass and center of pressure determine the stability of the rocket during flight.
A rocket achieves lift off due to what?
Burning rocket fuel exerts pressure on the rocket nozzle. Note that this happens regardless of whether there is any air for the exhaust to push against. It is simply a matter of expanding gasses which exert pressure.
What is it called when combustion occur in a rocket's engine and releases heat and pressure making a larger pressure gradient inside the rocket than outside which causes the gaseous products?
This process is called thrust generation. The combustion of propellant in the rocket engine produces high-pressure gases that are expelled through a nozzle, creating a thrust force in the opposite direction as a reaction. This thrust force propels the rocket forward in accordance with Newton's third law of motion.
