How does the cloud in a bottle experiment work?
In this experiment, the alcohol acts like the dust, providing something cool for water droplets to attach to. When you pressurize the soda bottle by pumping air in, the air molecules collide with each other and warm the bottle. Releasing the pressure causes the water vapor to condense quickly, forming a cloud.
How does a water bottle rocket work?
Rockets work by ejecting something out of the back and a so-called ‘reaction force’ then pushes the body of the rocket forward. The energy to force the water out is stored as air pressure inside the bottle. You supply the energy as you pump air into the bottle. The air pressure inside builds up and pushes on the water.
How do whoosh rockets work?
The whoosh rocket replaces the heavy water with a much lighter, combustible, alcohol-air mixture. The pressurization of the bottle occurs during the combustion of the alcohol. When the thrust is greater than the weight of the bottle, the rocket accelerates up the rail as described by Newton’s first law.
Can you make a cloud in a bottle?
For example, take a cold water bottle outside on a warm day. You will notice that water droplets form on the outside of the bottle. These droplets are water vapor from the atmosphere condensing on the surface of the bottle. Water vapor in the atmosphere cools and condenses on particles in the air, creating a cloud.
What is the purpose of cloud in a bottle?
When you pumped air into the bottle’s enclosed space in this cloud in a bottle experiment, it forced the water vapor to squeeze together (or to compress). Releasing the pressure quickly allowed the air in the bottle to expand quickly. As a result, the temperature of the air in the bottle became slightly cooler.
Why did nothing happen when there was no smoke or moisture in the bottle?
You’ll notice that nothing happens. Why? The squeeze represents the warming that occurs in the atmosphere. The release represents the cooling that occurs in the atmosphere.
