Air Pressure Experiment Analysis

Dalia and Diane demonstrate an experiment involving a candle, water, and a flask. They explain the materials needed, set up the experiment, and describe the scientific principles observed. The experiment shows how air pressure changes when a candle burns inside a flask, causing water to be pushed into the flask as the air cools and pressure decreases.

Who are the presenters of the experiment?

• Dalia and Mike

• Diane and John

• Dalia and Diane

• Dalia and John

What is the purpose of using Play-Doh in the experiment?

• To light the candle

• To measure the water

• To hold the candle in place

• To color the water

What is the first step in conducting the experiment?

• Lighting the candle

• Adding food coloring

• Placing the candle in the center

• Pouring water into the pie dish

What happens to the air inside the flask when the candle is burning?

• It cools down

• It turns into water

• It expands

• It remains the same

Why does the water get pushed into the flask?

• Because of decreased air pressure inside

• Because of increased water pressure outside

• Because of decreased water pressure outside

• Because of increased air pressure inside

What is the role of the candle in the experiment?

• To create a vacuum

• To use up oxygen

• To add color to the water

• To heat the water

What causes the air pressure inside the flask to decrease?

• The water boiling

• The candle burning out

• The air being heated

• The flask being sealed

What is the main scientific principle demonstrated in this experiment?

• Air pressure

• Magnetism

• Gravity

• Electricity
