How does the density of a substance depend on temperature? Explain with a mathematical formula?

Density does not change as long as temperature remains the same. For every substance, the number of particles in a given volume remain constant if the temperature is kept constant. As the temperature is increased, the particles move more quickly and farther apart, thus increasing the substance's volume. When this happens, the density (which is the mass to volume ratio) decreases because mass remains constant, but volume increases.
