They observe that the hot water floats on the room-temperature water and the cold water sinks. Students will combine the concepts of temperature, molecular motion, and density to learn that hot water is less dense than room-temperature water and that cold water is more dense.

If density is directly proportionate to pressure and inversely proportionate to temperature, this would suggest that as temperature and pressure decrease with altitude, density would increase? This would also suggest that the atmosphere in the stratosphere was more dense than in the troposphere because the temperature and pressure are lower.

One of the Physics topics commonly practiced in school and your Physics tuition is the concept of density and pressure. Density and pressure have an integral relationship. The higher the density of an object that is exerting the pressure, the higher the pressure on the object on which the pressure is being exerted. It follows that the higher the pressure exerted on an object, the higher will be its density because the object will be compressed. This is especially true for liquids and gases.

The density of a liquid will change with temperature and pressure. The density of water versus temperature and pressure is indicated below:. See also Water - Density, Specific Weight and Thermal Expantion Coefficient , for online calculator, figures and tables showing changes with temperature. With 1 and 3b the final density after a temperature change can be expressed as. The influence of pressure on the volume of a liquid can be expressed with the three dimensional Hooke's law.

Nonequilibrium statistical mechanics via density fluctuation theory predicts relations between the bulk and shear viscosity, thermal conductivity, and self-diffusion coefficient of a fluid.

Matter most commonly exists as a solid, liquid, or gas; these states are known as the three common phases of matter. We will look at each of these phases in detail in this section. Solids are rigid and have specific shapes and definite volumes. The atoms or molecules in a solid are in close proximity to each other, and there is a significant force between these molecules. Solids will take a form determined by the nature of these forces between the molecules.

Temperature Effects on Density Density Density is the mass of any material per unit volume. Gases always have much lower density than the condensed phases. Most materials have a lower density of the liquid than the solid but this isn't always true. Water has a higher density in the liquid state than the solid, so ice cubes float. Within a particular phase, how does the density depend on temperature? Remember that temperature is related to the average kinetic energy of the atoms or molecules within the substance.

Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles. The more kinetic energy a substance has, the warmer it will be and the faster particles will be moving, which reduces the density of the substance. When temperatures rise, the air becomes less dense and rises, which is known as a low pressure system. When temperatures fall, the air becomes more dense and is known as a high pressure system.
