Step 1
Fill the glass about half-full with water.
Step 2Pour the salt into the glass. Mix the salt into the water with the spoon. Stir until the salt dissolves.
Step 3Slowly add more water to the glass until it's almost full. Do this carefully, so that the fresh tap water won't mix with the salt water in the glass.
Step 4Gently place the egg into the glass of fresh and salt water. Watch as the egg falls through the plain water at the top of the glass but floats in the salt water.
a egg can float in salt water because the water is denser than the egg
When you soak an egg in salt water, the egg will float because the salt water is denser than the egg, decreasing its overall density. This is due to the process of osmosis, where water moves from an area of low salt concentration (inside the egg) to an area of high salt concentration (the salt water), causing the egg to float.
Yes, and egg will float in salt water.
How much salt water is present is not important, the problem is what is the concentration of salt in the water. The saltier it is, the denser the salt water becomes. If the salt water is denser in comparison to the density of the egg (which will more or less vary with each egg), then the egg will float; if not, then the egg will sink.
An egg floats in salt water because the density of the salt water is higher than the density of the egg. The higher density of the salt water creates an upward buoyant force on the egg, causing it to float.
The egg will be more bouyant in salt water.
When an egg with its shell removed is placed in salt water, the water will move from the egg into the salt water due to osmosis. This will cause the egg to shrivel and shrink in size as water leaves its membrane to balance out the concentration of salt inside and outside the egg.
An egg will lose mass in salt water because of osmosis. Water flows out of the egg into the salt water solution, which has a higher concentration of solutes. This results in the egg losing water and mass.
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
Because the salt water is more dense than the egg.
An egg does float in water that is mixed with salt, because salt provides more density in the water, and ,therefore, allows an egg to float.
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.
