## Why do fruit juices rise through a straw when we drink through it?

That’s because the atmosphere is pushing down on the liquid in the glass. The atmosphere pushes the liquid in the glass up into the straw. Now the atmosphere is pushing down on the liquid in the glass, with noting the balance it inside the straw, so the liquid rises…into your mouth!

## How are we able to drink a liquid with the help of a straw explain briefly Class 8?

Explanation: when you drink from straw, you create a little space of low pressure inside your mouth and in top of the straw. Then the air inside the straw pushes down on the surface of the drink and forces the liquid to go up through the straw and then in your mouth.

When drinking through a straw you reduce?

When drinking through a straw, you reduce the pressure in your mouth and the air pressure moves the liquid.

How does a straw works?

A straw works because when you suck the air out of the straw, it creates a vacuum. When you suck the air out of the straw, you decrease the pressure inside the straw, allowing the higher pressure on the rest of the surface to push the tea up the straw and into your mouth.

### When drinking through a straw you reduce the pressure in your mouth and the atmosphere moves the liquid could you use a straw to drink on the moon explain?

A straw works because when you suck the air out of the straw, it creates a vacuum. This causes a decrease in air pressure on the inside of the straw. Since the atmospheric pressure is greater on the outside of the straw, liquid is forced into and up the straw and into your mouth (Figure 11.1. 1).

### How do straws work would they work in space How do you know?

You could put an industrial vacuum pump on the straw and it won’t get a drop (not unless you count water vapor). It can’t, because there is no such force as “suction,” only atmospheric pressure rushing in to fill the void. On the moon (outside a pressurized habitat) there is no air pressure, so straws don’t work.
