Cloud Formation Experiment Questions

The video tutorial explains how to create a cloud in a bottle using water, a plastic bottle, and matches. It describes the process of saturating the air inside the bottle, using smoke particles from a match as condensation nuclei, and manipulating pressure to form visible clouds. The scientific principles behind cloud formation, such as pressure changes and condensation, are also discussed.

What are the three materials needed to create a cloud in a bottle?

• Water, a plastic bottle, and a match

• Water, a glass bottle, and a candle

• Water, a metal bottle, and a lighter

• Water, a plastic bottle, and a flashlight

How full should the bottle be filled with water for the experiment?

• 3/4 full

• 1/4 full

• Completely full

• Half full

What is the purpose of shaking the bottle after adding water?

• To warm up the water

• To mix the water with air

• To saturate the air with water vapor

• To clean the bottle

Why is a match used in the experiment?

• To create light

• To add smoke particles

• To heat the water

• To make a sound

What happens when you squeeze the bottle after adding the match?

• The water changes color

• The bottle breaks

• The water evaporates

• A cloud forms

What are condensation nuclei?

• Large water droplets

• Ice crystals

• Tiny smoke particles

• Air bubbles

What is the role of condensation nuclei in cloud formation?

• They decrease the pressure

• They increase the temperature

• They provide a surface for water droplets to form

• They absorb water

What happens to the pressure and temperature when you squeeze the bottle?

• Both increase

• Both decrease

• Pressure decreases and temperature increases

• Pressure increases and temperature decreases

What allows the water to cool and condense in the bottle?

• Decreasing the pressure

• Increasing the pressure

• Shaking the bottle

• Adding more water
