Why Is Density Fixed?

Why Is Density Fixed? The density of a substance changes when it changes state. Its mass does not change. This is because its particles do not disappear – they are just rearranged and occupy a different volume . Why is density considered a fixed property of matter? Because it is a ratio, the density of

How Does Temperature Affect Density Of Solids?

How Does Temperature Affect Density Of Solids? 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. Can you change the density of a

How Are The Density And Temperature Of Air Related?

How Are The Density And Temperature Of Air Related? Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases. Why is density inversely proportional to temperature? Density is directly proportional to pressure because high pressure results in
