What is on the surface of an egg when in vinegar?
air bubbles
What happen in an egg when it placed in a salt solution?
The salt water egg experiment is to demonstrate that salt water is denser so the egg floats. When the egg is placed in pure water, the egg sinks because pure water is less dense than salt water.
How do you know the egg will sink and water will float?
Normaly if an egg floats it is bad and should be discarded. As the egg ages air pockets enter the egg, that's why they float. A change in buoyancy. If the egg is more dense then the water (or whatever liquid it is in), it will sink.
What would happen to an egg if you sent it into space with a weather balloon?
Depends on the porosity of the egg shell in question. If it is not porous then the air pocket would be at a higher pressure than the outside of the egg and it would fracture. If the egg is porous then the air within the air pocket would escape from the shell as the weather balloon ascended and probably won't fracture the egg.Whether the proteinaceous matter would burst the shell, I doubt it as it is solid, covalently bonded/hydrogen bonded matter- UNLESS there are tiny air bubbles within the matrixes of matter... in which case they could expand.Only one way to find out...( a prompt for meteorologists)
What egg will float faster an egg with cold water or an egg with hot water?
Cold water.

air bubbles
What happens if egg is put to Hcl and then water?
The egg in HCl reacts violently as the calcium carbonate on the outer surface of egg is dissolved. This is what actually happens : The egg in the hydrochloric acid is lighter, because the gas bubbles provide a floatation device, than the acid so it stayed at the top. The bubbles occurred because the calcium carbonate on the egg shell reacted with the acid. Carbon dioxide bubbles are produced, causing the egg to rotate and spin. The carbon dioxide bubbles on top of the eggs break. In the meantime more bubbles are attached to the bottom of the egg. These bubbles now cause the egg to spin and repeat the process. The bubbles attached to the egg also made it less dense. After this experiment, the egg will not have a shell. It will have dissolved. then when you place this egg in water, Osmosis takes place. Well, the egg is 90% water. So now when you keep the egg in water it kind of pushes the egg membrane. Basically, water is flowing into the egg and the egg swells as the water enters it.
What is the best raising agent for a Swiss roll?
when the egg and sugar are whisked, the egg traps air bubbles. you must whisk for a couple of minutes. When the Swiss roll is cooked, these air bubbles expand with the heat, rising the cake!
What came out in one or two places while heating the egg?
I think I remember learning this a few years ago. If you mean a hard boiled egg, when heated in water, air bubbles escape through tiny holes in the egg's shell. -Rocklegend51
Why when you drop an egg on hot water bubbles rise?
When water is near the boiling point, there are micro-bubbles in the water, where the vapour pressure is equal to the surrounding water pressure plus the micro-bubble surface tension. This process is known as superheating. When an egg, or other object, is dropped into the superheated water, the surface tension is broken, and several micro-bubbles join together to form a single bubble visible to the naked eye. This process then is self-agitating, and creates more bubbles. This is the reason you should never boil water in the microwave, as it can instantaneously boil over and scald you.
Will an egg break if you drop it inside water?
If the egg is submerged when you release it, No.
Scientifically speaking what part do eggs play when added to a cake mix?
Beaten eggs form a layer around the air bubbles in the cake. when heated the whits of the egg coagulates and becomes rigid preventing the air bubbles from bursting and the cake from collapsing.
Can you treat the wellfor water that has a egg smell?
The "egg smell" is hydrogen sulfide gas, which can be dissolved in well water. It's mostly just stinky and tastes bad, but in high enough concentrations, it can kill you. There are various charcoal filters you can install, but an aeration system that bubbles the water up into the air and then collects the water will often reduce the HS concentrations substantially, by allowing the HS to blow away into the atmosphere.
Why does the egg float in the water?
There is a small air-sac at one one of the egg (intended to supply air to a developing embryo) - that makes it buoyant.
Why do you use aeration making meringues?
You want small bubbles of air to lift the egg white protean so that the meringues will be light and crisp after baking.
What happens to an egg when you put it in molasses?
Backing up for a second, you have to know what happens to an egg in tap water. Tap water is less dense than an egg; therefore, the egg will sink.Then you have to take a look at soda water. Soda water is tap water with a gas (CO2) dissolved in it. Water will not naturally be carbonated unless the two substances are put under pressure (excluding fermentation), thereby forcing the gas to be dissolved in the water. If the soda is not under pressure, the carbon dioxide will naturally "undissolve" from the water. Since the carbon dioxide is also less dense than the water, it will "undissolve" from the water and float out of the container.In addition, the overall density of the soda water will change due to the added CO2, although it may not change much. Really, it depends on the concentration of the CO2 (how carbonated it is), which determines the volume. Density is defined as mass divided by volume. The CO2 is being added to the water and is less dense, so the density will already be decreasing. But the CO2 also adds volume to the solution, which also deceases the density (due to CO2's relative zero mass). The most we can say is that soda water is less dense than regular water, but since the degree of carbonation is not known, it is unsure how less dense it is.So you put the egg in. What happens? Well, we know that an egg will sink in tap water because the tap water isn't dense enough. We also know that the soda water is going to be slightly less dense than the water. So the egg is going to have to sink.But this isn't the end of the story. Although the egg looks smooth, its surface is in fact porous enough for the bubbles to lodge into. Depending on the carbonation and amount of bubbles that form, the bubbles could attach to the shell of the egg. Because the bubbles are "undissolving" and are less dense than water, they are already on their way to the surface. Moreover, when the bubbles lodge onto the egg, the egg and bubbles overall volume will increase without the mass changing (because of CO2's relative no mass). The overall volume increases without the mass increasing, so the egg will become less dense. This, and the conjunction of the buoyancy caused by rising bubbles, could in fact lift the egg back to the top of the water. Again, this would have to be determined by the amount of carbonation. If the egg does return to the surface, some bubbles may dislodge from the egg or burst, in which the opposite process may happen and the egg will sink again. This process may repeat itself many times.
Why does an egg float in a beaker of water?
Eggs are porous. The older the egg the more air contained within the egg shell. As the albumen inside the egg dries out with age, it is replaced by air. Fresh eggs will not float.
