Density determines how far apart molecules of a material are from one another, i.e. Density is the mass per unit of space. Due to this, density is related to the rate of heat transfer or thermal energy transfer. Thermal energy being transferred relies on the difference in the internal energy of molecules, mostly kinetic energy, as when heat is transferred, these molecules exchange energy by hitting into each other. By doing so, eventually thermal equilibrium is established.
Summary - Density is related to the rate of heat transfer between two systems.
Generally, density and thermal energy are directly proportional to each other. As an object or system becomes less dense, particles are moving more and colliding with each other in order to do so. Thermal energy exists partially as kinetic energy, and as this movement occurs, thermal energy is used up and as a result, less thermal energy remains. So, anything that loses density usually loses thermal energy as well. Questions?
The specific heat capacity of air at constant pressure is a (weak) function of temperature. The density varies inversely with temperature when pressure is constant.
Think of these two factors in terms of a positive correlation. For example, the higher the temperature, the higher the density.
For basic Earth Science students, there is none.
All substances have a so called Specific Heat which defines the thermal energy possessed relative to water, which has 1 calorie per gram per degC.So it is the mass of the sample of the material that determines its thermal energy content, not its density.

In this case the volume increase, the density is lower.

If the thermal energy is higher, then the particles in the object move faster and want to get away from each other because it is so hot, thus, its a gas. If the thermal energy is lower, then the particles in the object move slower and form a solid shape, like they are huddling together, thus, its a solid. If the thermal energy is right in between the two above, then it is a liquid. A great example is H2O, it is the base measurement of density, when its thermal energy rises, it turns into water vapor, if its thermal energy lowers, it turns to ice.
