What is an exception to the density rule?

What is an exception to the density rule?

The density of a substance usually decreases as temperature increases. One familiar exception to this rule is water. Ice floats in liquid water, so ice must be less dense than liquid water. Usually, substances expand and become less dense when they are warmer, and shrink and become more dense when they are colder.

Why is water an exception to the above rule that solids are more dense than liquids?

Water is different from most substances: it is less dense as a solid than as a liquid, because its particles move apart slightly on freezing. This is why ice cubes and icebergs float on liquid water.

What common substance is an exception to the general rule that solids are more dense than liquids?

water
…..why is water an exception to this: Well water is an exception despite being a liquid, but not all solids.. This follows the principle of flotation the same thing that makes ice (which is a solid) floats because it’s less dense..

Are liquids always less dense than solids?

Solids are usually much more dense than liquids and gases, but not always. Mercury, a metallic element that is a liquid at room temperature, is denser than many solids. Aerogel, a very unusual human-made solid, is about 500 times less dense than water.

Why do solids and liquids have different densities?

The difference between the densities of solids, liquids and gases is due to the distance between the particles in each state of matter.

Why liquids Cannot be compressed easily?

Because the particles can move, liquids don’t have a definite shape, and they can flow. Because the particles are still packed close together, liquids can’t easily be compressed and keep the same volume.

Is liquid less dense than solids?

In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them. The particles in a liquid usually are still touching but there are some spaces between them.

Are all liquids denser than solids?

Why does a solid have a higher density than a liquid?

Normally when liquid gets solidify, the international molecular forces becoming more and more and inter molecular space decreases, so that the density of solid is more than its liquid. But, in case of water it quite different.

Why does ice have less density than liquid water?

When liquid water solidified, it aquires a tetrahedral open cage like lattice structure with four inter molecular hydrogen bonds. Due to this the effective volume of ice becomes slightly more than its liquid state hence ice (solid form of liquid water) has less density than liquid water. Therefore ice always floats over its liquid surface.

Which is a solid that floats in water?

Example, Ice is a solid and floats in its liquid state water. Ice floats in water because it is less dense than water. So any substance that has a lower density in its solid state than in its liquid state will float.

Can a substance float in a liquid state?

So any substance that has a lower density in its solid state than in its liquid state will float. While a number of compound materials (like salts and alloys) have this property, only 5 elements on the periodic table are known to have a density that is greater in their liquid phase.
