Does An Old Egg Float Or Sink

Have you ever wondered why an egg floats in water? Or why it sinks? The answer has to do with the density of the egg and the density of the water. Density is a measure of how much mass an object has for its size. The more mass an object has, the denser it is. The denser an object is, the more force it takes to move it.

Eggs are mostly made up of water, but they also contain protein and fat. Protein and fat are denser than water, so an egg is denser than water. This means that an egg will sink in water. However, if you add salt to the water, the water will become denser. This is because salt dissolves in water and takes up space. When the water becomes denser, the egg will become less dense in comparison. This means that the egg will float in the salt water.

The age of an egg also affects whether it will float or sink. As an egg gets older, it loses water and gains air. This makes the egg less dense. As a result, an old egg will float in water, while a fresh egg will sink.

So, the next time you're wondering whether an egg will float or sink, just think about its density. If the egg is denser than water, it will sink. If the egg is less dense than water, it will float.

Here is a simple experiment you can do to test this out. Get a glass of water and add a fresh egg to it. The egg will sink to the bottom of the glass. Now, add a tablespoon of salt to the water and stir it until the salt dissolves. The egg will now float to the top of the glass.

This experiment shows that the density of an egg is greater than the density of water, but less than the density of saltwater.
