What happened to the non inflated balloon when you placed the empty glass bottle in a bath of hot water?

As the air in the bottle cools down, the molecules of the air slow down and take up less space because they move closer together. The air then moves out of the balloon and back into the bottle, causing the balloon to deflate.

What happened to the empty plastic bottle after it was placed in hot water?

What is this? 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!

What caused the diver to dive when the bottle was squeezed?

The reason the diver sinks when you squeeze the bottle is because the pressure exerted on the water collapses the sides of the pipette. Squeeze the bottle and watch how the sides of the pipette cave inward. This decreases the volume of the diver.

Why it is written crush the bottle after use?

Have you ever wondered why is “Crush after use” written at the bottom of plastic water bottles? This sure does have a solid reason. Plastic water bottles have a tendency to accumulate germs in them after the initial usage. This is why crushing the water bottle after emptying it is important.

What happens to the balloon in the bottle with hot water?

Putting the bottle in hot water causes the air molecules inside to heat up and begin taking up more space (thermal expansion), causing air to enter the balloon and inflate it. When you move the bottle into the cold water, the air molecules cool back down and take up less space (thermal contraction).

What happens to the set up where the hot water is inside the bottle found at the bottom while the cold water is found in the top bottle?

So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top, mixing with the cold water along the way and creating purple water.

Can you drink bottled water left in the car?

Bottled water is fine. You can drink it — just don’t leave it in a hot temperature for a long time. I think that’s the important message,” Lena Ma, the study’s co-author and a professor of biogeochemistry of trace metals at the University of Florida, told Yahoo Health.

What is the role of the force exerted on the bottle to the floating and sinking of the eye dropper?

Squeezing the bottle causes the diver (the eye dropper) to sink because the increased pressure forces water up into the diver, compressing the air at the top of the eye dropper. This increases the mass, and density, of the diver causing it to sink.

What does PET mean on bottle?

Polyethylene terephthalate
Polyethylene terephthalate, also called PET, is the name of a type of clear, strong, lightweight and 100% recyclable plastic. Unlike other types of plastic, PET is not single use. PET is 100% recyclable, versatile and is made to be remade. That’s why, America’s beverage companies use it to make our beverage bottles.

What did you notice to the balloons inside the bottle?

When a balloon is placed inside the bottle, it will not inflate, since the bottle is already filled with air particles with no escape route. This is a great demonstration that air takes up space. The air inside the bottle compresses a little bit but not enough to permit the balloon to inflate.

What happens to the pressure inside the bottle when the balloon expands?

Air molecules collide into the balloon with the same energy inside and outside the balloon. When the bottle is heated, the air molecules inside start moving faster. These molecules now collide into the balloon with more energy resulting in increased pressure.

How will we get the egg out how do we increase the pressure inside the bottle?

To get the egg out of the bottle, turn the bottle upside down and blow into it, so that the egg acts as a one-way valve. The increased air pressure in the bottle will cause the egg to pop back out.

What happens to the water at the bottom of the bottle when it is placed under the sun?

Leaving a case of water bottles in the sun will not cause dangerous chemicals to break down in the water, although heat can affect the integrity of the bottle and change the taste of the water.

Can you drink yesterday’s water?

You should avoid drinking water left open for a very long time. The water left overnight or for a long period of time in an open glass or container is home to numerous bacterias and is not safe for drinking. You never know how much dust, debris, and other small microscopic particles might have passed into that glass.
