density per unit area

The density of the members belonging to this group is found to increase down the group as usual. Explanation: It is because of the increase in mass per unit volum..

0.5 kg of cotton occupies more space than 0.5 kg of iron. The particles of iron are closely packed while that of cotton are loosely packed. The amount of iron packed in a unit volume is more. This explains as to why iron is heavier than the same volume of cotton. In Physics, we describe t..

It is the total number of individuals of a species per unit area or volume at a given time. (Such as number of animals per square kilometre or number of trees per area etc.) Population density reflects the success of a species in any given area. Po..

Population Density - It is the most important parameter indicating the pressure of population on land, water and other resources. Usually, higher population density (expressed as number of people (square kilometers) is found in urban areas than in rural areas..

Which of these units would be the most appropriate for measuring the area of a lake? => square miles or miles or cubic meters or cubic liters..

Now, if we take equal volumes of the substance and of water, then the above becomes, As the relative density is a ratio of two similar quantities it has no unit..

The maximum height of mercury, which can be supported by the atmospheric pressure provides a measure of that pressure. A standard pressure of one atmosphere (1 atm) is defined as the pressure that will support a column of mercury of 76 cm height at 0C (density of mercury (13.5951 gcm - ..
