Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

In water conversation, chemistry spread a thin certain inert materials over the surface of water cut down on the rate of evaporation of water in reservoirs. This technique was pioneered by Benjamin Franklin three centuries ago. Franklin found that 0.10mL of oil could spread the surface of water of about 42.9m2 in area. Assuming that oil forms a monolayer ( that is, a layer that is only one molecules are roughly cubic. (1mm=1*10^-9m)
