What does the balloon inside the bottle represent?

What does the balloon inside the bottle represent?

Which parts of the model lung represent the lungs, chest cavity, rib cage, and diaphragm? (The small balloon inside the bottle represents the lung. The bottle represents the chest cavity and the rib cage. The plastic /balloon handle represents the diaphragm.)

What happens to the balloon inside the bottle when you try to inflate it with the hole plugged and unplugged?

Science Background When the bottle with the hole is used, however, inflating the balloon is nearly effortless. The air inside the bottle is able to escape, freeing up space for the balloon to now inflate. If you then plug the hole on the outside of the bottle, the balloon will remain inflated.

What is the reason why the balloon can’t be blown in the first bottle but when transfer to a bigger bottle it can be?

How Does It Work? The balloon won’t inflate much the first time because the bottle is already filled with air. There’s no room for the balloon to expand inside the bottle. However, when you punch a hole in the bottle, the air molecules in the bottle have an exit.

What cause the deflation of the balloon inside the bottle?

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 happens when you pull down the balloon?

When you pulled down on the knot, the balloon inflated slightly and when let go the balloon deflated! Inside your body, you have two lungs that work together, and the diaphragm is below them. Air goes in and out of both of your lungs at the same time.

What happens to a balloon if you place it on a boiling water?

WHAT IS HAPPENING? When you stretch the balloon over the opening of the bottle, all of the air is trapped inside. 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.

What happens when you inhale when you push up on the bottom balloon?

1. Describe what happens when you inhale (when you pull down on the bottom balloon in your model). The balloons (your lungs) inflate, take in more air, or get bigger. Technical Explanation: During inhalation, the diaphragm contracts downward, and rib muscles pull upward, causing air to fill the lungs.

What happened to the two small balloon as you push up the big balloon at the bottom?

What happens to the two small balloons as you push up the big balloon at the bottom? When you pull down the balloon in the bottom, the two small balloons will increased in volume or expand. When the pressure decreases, the surrounding air particle will enter the two balloon and causes it to expand.

What happens when you blow a balloon into a bottle?

When you blow air into the balloon you increase the pressure inside and this pushes or expands the balloon. But it also squeezes on the trapped air inside the bottle, increasing its air pressure exactly as much as inside the balloon.

What happens when you turn off the hot plate on a balloon?

The balloon will fill up with hot air and stand straight up. When that happens, turn off the hot plate and leave the bottle on the hot hot plate. DON’T touch the glass! It will be very hot. Use the hot pad to remove the bottle to a heat-safe location so the glass can cool. Watch what happens to the balloon as the bottle cools.

How does hot water cause a balloon to inflate?

When the bottle is placed into the pan of hot water, the heat from the water causes the air inside the bottle to heat up. As the air in the bottle heats up, the molecules of the air begin to move faster and take up more space. The air from the bottle then moves into the balloon causing it to inflate.

What happens at the bottom of a balloon?

At the bottom, it’s heated again and rises in the center in a steady up and down “convective” flow. It’s likely that convection is occurring inside the sealed bottle as heated air rises into the balloon, cools, and then falls back into the bottle to be heated again.
