A student in the laboratory plans to exert a vacuum in the air space above the surface
Question:
A student in the laboratory plans to exert a vacuum in the air space above the surface of water in a closed tank. She plans for the absolute pressure in the air to be 12,300 Pa. The temperature in the lab is 20°C. Will water boil under these circumstances?
Step by Step Answer:
The boiling point of water is dependent on the pressure at which it is bein...View the full answer

In this video, the concept of pressure has been explained. The bottle is filled up with water, remove the pipe, and now you can see the clear flow of water from the holes due to liquid pressure.You can see that the second layer is holding the weight of the first layer and the third layer holding the weight of both upper layers, that’s why liquid flows out wider from the third as compared to the first two.At the first hole, water doesn’t roll along the walls; it flows out at an angle.At the second hole, you’ll see that the water flows out at a wider angle as compared to the first hole.At the third hole, we can see that the flow of water is much wider/greater than the other holes.This proves that the pressure at the bottom of the bottle is much more than the pressure at the top layers.
