Does An Egg Sink Or Float

When placed in water, an egg can either sink or float, depending on its density relative to the density of water. The density of an object is defined as its mass per unit volume. The density of water is approximately 1 gram per cubic centimeter (g/cm³). If the density of an egg is greater than 1 g/cm³, it will sink. If the density of an egg is less than 1 g/cm³, it will float.

The density of an egg is determined by its composition. Eggs are composed of protein, fat, water, and minerals. The protein and fat content of an egg are denser than water, while the water content of an egg is less dense than water. The overall density of an egg is therefore determined by the relative proportions of these components.

The age of an egg can also affect its density. As an egg ages, it loses water through evaporation. This causes the density of the egg to increase. As a result, older eggs are more likely to sink in water than fresh eggs.

The temperature of water can also affect whether an egg sinks or floats. When water is heated, its density decreases. This is because the molecules of water become more energetic and move further apart. As a result, an egg is more likely to float in warm water than in cold water.

The following table shows the density of eggs at different ages and temperatures:

| Age of egg | Density (g/cm³) | |---|---| | Fresh | 1.036 | | 1 week old | 1.040 | | 2 weeks old | 1.044 | | 3 weeks old | 1.048 |

As you can see from the table, the density of an egg increases as it ages. This is because the egg loses water through evaporation, which causes the density of the egg to increase. The temperature of water also affects the density of an egg. An egg is more likely to float in warm water than in cold water.
