## What happens to balloons when rubber sheet is released?

When the rubber sheet is pushed upwards into a dome shape, the balloons become deflated. This is because the air volume inside the bell jar decreases, thus increasing the air pressure. As a result, the volume of the balloons decreases and the pressure increases. Air is forced out of the balloons.

Why does air rush in when the rubber sheet is pulled down?

(3 marks) When the sheet is pulled down, the volume in the jar increasesThis causes the pressure in the jar to decreaseTherefore, air enters the balloon, down the pressure gradient, causing the inflation.

When we pull the rubber sheet downwards the space inside the bottle?

In the given experimental set up, when the rubber sheet is pulled down, the space in the bottle increases and the balloons inside the jar get inflated. If the balloons represent the lungs, the rubber sheet is the diaphragm and the plastic bottle is equivalent to the chest cavity, then this set up represents inhalation.

### Why do the balloons inflate when the plastic sheet is pulled down?

The balloon at the bottom works like your diaphragm—a strong muscle that expands and contracts to cause your lungs to fill with air and then empty out again. When you pulled down on the knot, the balloon inflated slightly and when let go the balloon deflated!

What will happen when the thin rubber sheet is pushed upwards?

Answer: When the diaphragm (rubber sheet) moves up, the volume inside the glass jar (thorax) decreases. This decrease in volume causes an increase in pressure. The lungs (balloons) deflate as air exits until the pressures inside and outside are equal.

What happens when you inhale when you pull down the balloon at the bottom?

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 happens to the pressure inside the bell jar when the stretchy rubber is pulled downwards?

The bell jar model As the rubber sheet is pulled down the volume of the jar increases, the pressure therefore decreases and air is drawn in through the glass tube inflating the balloons, which represent the lungs.

What happen when you inhale when you pull down the balloon wrap at the bottom?

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 happens to the space inside the bell jar when the stretchy rubber is pulled downwards?

### What happen if you inflate the balloon more?

As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands… up to a point, that is! If you put in too much helium, and the pressure inside the balloon exceeds the atmospheric pressure on the outside of the balloon, the balloon will burst.
