What happens to the air pressure in the bottle when you blow?
Because it sends vibrations through the bottle to make a sound
Why is it not advisable to use a ground glass stopper for a reagent bottle containing sodium hydroxide solution?
Over time, the sodium hydroxide will react with the smidges of carbon dioxide in air to produce sodium carbonate, the white, crusty powder that you find around the rim of plastic capped stock bottles (for example). This powder will either prevent the ground glass stopper from sealing properly and exposing the contents to more air, or will in fact cement the ground glass stopper in the bottle, and make it impossible to remove.
What happens to air pressure as low pressure moves into a area?
When a low pressure system moves in it will try to mix with the system currently in place. If that happens to be a high pressure system you will get thunder storms. If its a low pressure system then nothing changes.
How can air pressure be changed?
Using the equation P1V1/T1 = P2V2/T2 we find there are two variables we might influence in order to change the pressure of a gas. (P=pressure, V=volume, T=temperature in degrees Kelvin) By increasing or decreasing the temperature of the bottle, you can increase or decrease the pressure within. If the bottle is made of a flexible material, like plastic, you can apply pressure to the bottle. By either squeezing the bottle or increasing atmospheric pressure outside, you deform the bottle and decrease it's volume. Since the quantity of gas inside the bottle is constant, the decrease in volume increases the pressure. Likewise to decrease the pressure in a sealed flexible bottle, you can decrease air pressure outside.
Show by an activity that high speed winds by accompanied by reduced air pressure?
crumple a small piece of paper into a ball size smaller than the mouth of the empty bottle.hold the empty bottle on its side and place the paper ball just inside its mouth.now try to blow on the ball to force it into the bottle.try the activity with battles of different sizes. when we blow into the mouth of the bottle,the air near the mouth has higher speed. this decreases the pressure there . the air pressure inside the bottle is higher than near the mouth.
What happens to the pressure in a bottle of water if you press the stopper at the top down father?
The pressure will slightly increase.
When glass stopper in a bottle is stuck it may sometimes be loosened by holding the neck of the bottle under a hot water faucet explain the physical principle responsible for this observed phenomenon?
With a few exceptions (notably melting ice) objects expand when heated. If you run hot water on a bottle neck, the heat is applied directly to the bottle and only indirectly to the stopper inside the bottle, so the bottle heats first, and thereby expands sooner than the stopper does. An expanded bottle will exert less pressure on the stopper.
What is a bottle stopper?
Decanter
What is cook stopper?
A CORK stopper is a plug for a bottle made of cork
How do bottle rockets fly?
The 'operator' fills the bottle with water, then pumps air into it - creating pressure. When the stopper is released, the air pressure forces the water out of the narrow opening in the bottle's neck - creating a stream powerful enough to launch the rocket into the air.
How get glass stopper out of a glass bottle?
Grease the top of the bottle!
What is a wine bottle stopper?
Cork
What happens when you blow in a water bottle?
you increase the pressure
What is the use of beaker cover?
A beaker cover is called a rubber stopper or metal stopper(depends on what the stopper is made of).
Why should we place bottle stopper upside down one the bench?
to avoid contaminating the chemical when the stopper is replaced
What is the difference of dropping bottle and reagent bottle?
The reagent bottle is not used for dropping, having only a common stopper.
How do you get a stock glass stopper out of a bottle?
all you have to do is take the bottle to mars and ask the aliens to open it for you> yeah don't listen to that idiot> you just use pliars to carefully remove the stopper
