What happens when you put a match in a bottle?

What happens when you put a match in a bottle?

In this demonstration, the lit matches heat the air inside the bottle. When air is heated it expands and some of it escapes out the bottle. When the matches go out, the air inside the bottle cools and contracts (takes up less space), thus creating a lower air pressure area inside the bottle than outside.

What are the ingredients to make a cloud?

Students will discover that three main ingredients are needed for clouds to form: moisture, condensation, and temperature. 2. Evaporation and condensation are part of how a cloud forms.

What is the purpose of smoke in a bottle?

Why do we add smoke? The cloud effect is more dramatic when there are tiny particles in the air like smoke or dust. Those particles give the water molecules someplace to clump together as they form. So adding smoke particles to the bottle makes it easier for a cloud to form and easier to see.

What happens to the glass bottle when a lit piece of paper was placed inside?

Because the pressure of the air is pushing it. Before the burning paper was put into the bottle, the pressure of the air inside the bottle was the same as outside the bottle. As it cools, the air contracts, and the pressure of the air inside the bottle becomes less than the pressure outside.

What is inside the whoosh bottle?

A mixture of alcohol and air in a large polycarbonate bottle is ignited. The resulting rapid combustion reaction, often accompanied by a dramatic ‘whoosh’ sound and flames, demonstrates the large amount of chemical energy released in the combustion of alcohols.

What do combustion reactions produce?

Most combustion reactions produce carbon dioxide and water, so these chemicals are written as the products on the right of the equation. Charcoal is a fuel that contains carbon atoms but no hydrogen atoms.

What are the 4 ingredients of a cloud?

In able for a cloud to form, several ingredients must be in place:

• water.
• cooling air temperature.
• a surface to form on (nuclei)

Where does smoke in a bottle go?

When you release the bottle, the pressure decreases. This causes the temperature inside the bottle to fall and the water molecules to condense. The smoke particles act as cloud condensation nuclei, allowing the water molecules to condense and stick together around the smoke. There you go – a cloud in a bottle!
