What are the densities of solids, liquids, and gases?

Solids generally are denser than liquids and liquids denser than gases as a general rule because of space of particle seperation which affects freedom of molecular movement. However, there are exceptions to the rule depending on which elements being studied and analyzed. Mercury for example, is heavier in liquid form and quite dense. read more

Notice that the solid (steel) is the most dense, the gas (air) is the least dense, and the density of the liquid (water) is in between. Solids. The particles in solids are very close together. They are tightly packed, giving solids high densities. Liquids. The particles in liquids are close together. read more

6. Define the terms density and specific gravity. Given the density, and either the mass or volume, be able to determine the volume or mass (respectively). 7. Know that a liquid will boil when its vapor pressure is equal to the atmospheric pressure. 8. Describe, compare, and contrast amorphous solids and crystalline solids. 9. read more
