As temperature increases, the density of liquids and gases decreases; as temperature decreases, the density increases. Density is the amount of mass per unit of volume. More »

Temperature and salinity both affect the density of water. As the temperature of the water decreases, the density of the water increases. More »

Temperature affects the speed of sound by changing the density of the medium in which a sound wave travels. In most cases, when the temperature of a medium increases so does the speed of sound through that medium. More »

Wien's displacement law states that objects that absorb and emit radiation have radiated energy curves that are similar, but peaks at different wavelengths, depending on their temperatures; the wavelength of the maximum ... More »

The viscosity of liquids increases as temperature decreases, whereas the viscosity of gases increases as temperature increases. Viscosity is a fluid’s resistance to internal motion or flow and results from intermolecular... More »

The viscosity of a liquid decreases as the temperature is raised, while the viscosity of a gas increases as the temperature is raised. In a liquid, the increased temperature causes the molecules to move faster, which mea... More »

Heat conduction depends on the electronic configuration, density, temperature and dimensions of the material. Conduction should not be confused with conductivity, which is dimension independent. More »
