Question

In a sample of a gaseous substance, more than 99% of the overall volume ofthe sample is empty space. How is this fact reflected in the properties of agaseous substance, compared with the properties of a liquid or solidsubstance?

Answer 1

A gaseous substance is notable for having over 99% empty space, allowing it to compress, expand, and have a lower density compared to liquids and solids. The particles of a gas are also in constant motion, which facilitates the mixing of different gases.

Step-by-step explanation:

When comparing gaseous substances to liquids and solids, the fact that more than 99% of the volume of a gas is empty space significantly impacts its properties. Since the particles in a gas are spread out and in constant motion, gases have the ability to compress and expand, allowing them to fill the volume of any container. This also leads to a much lower density of gases compared to liquids or solids. Additionally, because of the significant amount of space between gas particles and their constant motion, different gases can mix freely with one another, leading to uniform mixtures such as air, which is a mixture of nitrogen, oxygen, and other gases.
