Why does the water shoot out a different distance from each hole?

The weight of the water in the bottle causing pressure causes the water to shoot out of the lowest hole the farthest. This is because the height of more water above the hole has more weight and creates a greater pressure that the hole that is higher on the bottle.

Why was it important to keep the lid or cap on the empty bottle as the experiment is done?

When we put the cap on the bottle, the hot air is trapped inside the bottle. The air pressure inside the bottle decreased to the point where it was less than the air pressure outside the bottle. Therefore, the air pressure pushing in was greater than the air pressure pushing out, causing the bottle to be crushed!

When the cap is on the top of a full bottle Why does no water come out the hole in the side of the bottle How does removing the cap make a difference?

Atmospheric pressure opposes the flow of water through the hole when the bottle cap is tight. The hole on the side of the bottle is open to the atmosphere and the pressure outside is almost one atmosphere.

How do you poke holes in plastic caps?

Purchase mixers in large plastic bottles and use a knife to poke a straw-sized hole in the bottle cap. Put three bendy straws together in a chain, secure with a slightly loose rubber band, and you’re all set!

What happens if we drill three holes at different heights in a plastic bottle filled with water?

Answer: the water from lower hole will come with high pressure and low pressure with upper hole.

At what speed does the water exit the hole?

5.2 meters per second
Thus, the speed of the water coming out of the hole is 5.2 meters per second.

Was the empty bottle really empty?

Scientists call this absence of matter a vacuum. On Earth a cup or bottle can seem empty, but it is different than in truly empty space. There is not actually a vacuum inside of these containers, but air. Air is invisible to the human eye but is actually made of tiny particles that move around.

What happens when you squeeze an empty bottle?

When you squeeze the bottle, you increase the pressure inside which raises the temperature. When you let go, the pressure and temperature drop. With lower pressure and lower temperature, water vapor comes together in tiny droplets and a cloud forms.

What happens if we drill two holes at different heights in a plastic bottle filled with water?

When you removed your finger at the hole and at the same time drop the cup what happened?

First off, when you just held the cup and let your finger off the hole, the water was pulled down by gravity and thus water pressure pushes it out the hole. So what changes when you drop the cup and water? The cup and water begin falling at the same speed, and are actually weightless as they fall.
