🌍 Puzzles on Atmospheric Pressure
Atmospheric pressure is the force exerted by the weight of air on every object on Earth. Let's explore this invisible force with real-life examples and puzzles. Click on each button to reveal the answer!
🔍 Puzzle 1:
What happens to a tin can when steam is allowed to escape and cold water is poured on it?
The can collapses due to atmospheric pressure acting from outside, as the steam inside condenses.
🔍 Puzzle 2:
Why does the can collapse in the experiment with steam and cold water?
The pressure inside drops when steam condenses, and atmospheric pressure outside crushes the can.
🔍 Puzzle 3:
How does a straw work when you drink from it?
Sucking air out reduces pressure inside the straw. Atmospheric pressure pushes the liquid up into your mouth.
🔍 Puzzle 4:
What role does atmospheric pressure play in a rubber sucker sticking to a wall?
Air is forced out, creating low pressure inside. Atmospheric pressure outside presses it firmly against the wall.
🔍 Puzzle 5:
How does a syringe fill with liquid when the plunger is pulled up?
Pulling the plunger decreases pressure inside. Atmospheric pressure pushes the liquid into the syringe.
🔍 Puzzle 6:
What is the function of atmospheric pressure in a siphon?
It helps push water up into the siphon tube from the higher container to the lower one due to pressure difference.
🔍 Puzzle 7:
Why should a siphon tube be filled with water before starting the flow?
To remove air bubbles and create continuous water flow by atmospheric pressure and gravity.
🔍 Puzzle 8:
What causes the liquid to move up into the straw or syringe?
Atmospheric pressure is greater than the reduced pressure inside, so it pushes the liquid upward.
🔍 Puzzle 9:
Why does water rise in a fountain pen when the piston is pulled?
Reduced pressure inside the pen causes atmospheric pressure to push ink or water up into the chamber.
🔍 Puzzle 10:
Why does a rubber sucker fall off the wall after some time?
Air slowly leaks in, equalizing the pressure, so the atmospheric pressure no longer holds it in place.
