🔍Air takes up space and affects the inflation of the balloon inside the bottle.
💦Creating a small hole in the bottle allows air to escape, making room for inflating the balloon.
🌀When the hole is sealed, the balloon stays inflated due to the absence of outside air flow.
🌬️Air pressure is the force exerted by the weight of air molecules above and around us.
🎈The Weather and Water experiment provides a hands-on understanding of air pressure concepts.
What is air pressure?
—Air pressure is the force exerted by the weight of air molecules above and around us.
Why does the balloon not inflate without a hole in the bottle?
—Without a hole, the air inside the bottle has no space to expand, preventing the balloon from inflating.
What happens when a hole is created in the bottle?
—The hole allows air to escape, creating room for the balloon to inflate.
Why does the balloon stay inflated when the hole is sealed?
—Sealing the hole prevents outside air from entering, keeping the air inside the balloon and maintaining its inflation.
What is the main purpose of this experiment?
—The experiment aims to demonstrate the concepts of air pressure and how it affects the inflation of objects, using a simple setup.
