Question

with very few exceptions the density of a substance to liquid .state is lower than the density of solids.state using the atomic model of mater .explain why this is the case?sketch diagrams showing the arrangement of models a solid and in a liquid to add your explanation.why do liquid flow.​

Answer 1

Answer:

Gases are less dense than solids and liquids because their molecules are far apart in comparison to solids and liquids. ... The greater the volumemass, the more dense the material is.

gaseous substance will occupy a much larger volume than a liquid or solid substance at the same temperature. Density is a function of mass per unit volume. A larger volume, like a gaseous substance would have, would lead to a smaller density.

When a substance is heated its volume increases and so the density decreases. In solids, increase in volume is negligible and hence decrease in density too. In liquids and gases, as the temperature increases, volume increases and therefore density decreases considerably.
