The arithmetic density of a population is the total number of people in proportion to the area of land (land size)
The physiological density of a population is the total population in proportion to the area of arable land.
Therefore, the arithmetic density of a population is always lower than the physiological density, since a land's arable portion can only be a subset of it's full size.
Arithmetic = (Population/Full size)
Physiological = (Population/Arable zones)

Arithmetic density is a population measurement that calculates the total number of people per unit of land area, while physiological density measures the number of people per unit of arable land. In essence, arithmetic density provides a broad measure of population distribution, whereas physiological density specifically focuses on population pressures on agricultural resources.
The density of platinumi s 21,45 g/cm3. The difference in density between isotopes is not significant.
Volume, mass, shape, density, to name a few.
Physiologic density is the number of people per unit of arable land. In the case of Pakistan, the physiologic density is likely less than the arithmetic population density due to large areas of arid or non-arable land. This means that while Pakistan may have a high total population, much of it may be concentrated in areas with better access to arable land.
To calculate the water difference when the density changes, you would need to account for the change in volume due to the density change. Use the formula: Difference in water volume = Original water volume / Original water density - Original water volume / New water density. Multiply this difference in volume by the new water density to obtain the actual water difference.
Actually, the amount of cultivated land per person is known as arable land per capita, not density. Density usually refers to the number of individuals in a given area, such as population density.
