And yes, time for activities in the kitchen to discover some physical phenomena that hide in cooking. We talk pots, milk bottles, popcorn, of pressure cooker, balloons and even ping-pong! Here's a nice program, is not it?
Thou then filled with water (about half of the bottle). Then you the places in a pot of water itself and also you do heat the whole (this is called a water bath).
By cons, during central kitchen sf cooling, as you have closed central kitchen sf with the cap, the air can not enter. Gold vapor condenses the bottle: water becomes liquid; occupies central kitchen sf a space much smaller and it brings down the pressure inside. It is the external pressure (atmospheric central kitchen sf pressure) which is higher that that crushes the bottle.
If you want to accentuate the phenomenon, you can place the bottle under cold running water. You'll then see the bottle slim down even further. Cold water was further accentuated the condensation in the bottle and the pressure inside has further fallen: central kitchen sf hence this intense deformation.
You need a rubber ball, a small glass bottle (or other glass container) and a pan. You fill the bottle with water (about 3/4 full) and you places the ball on the neck. You will have all in a pan (with or without water) and you heaters.
The water in your bottle will heat quickly and then begin boiling: it is also said that it vaporizes. Initially you can observe tiny bubbles that appear on the walls of the container. Then you'll see the mist on the top of the bottle.
You've probably had the experience of having a ping-pong all crushed. Unfortunately, you do no other hand. So what? What has happened? Under the influence of heat, the air in the ping-pong has heated himself too. The molecules that make up the have increasingly agitated, and took more space. It is the expansion of the air which has pushed the ball of the walls. It therefore returns to its original shape.
For even think a little pressure to the stories and vaporization in the kitchen Now that you understand that the pressure in a chamber could be changed by a heating and a state change, we will offer you the applications of these phenomena in some technologies, cooking recipes or natural phenomena!
