A Scottish chemist Thomas Graham observed and experimented with gas particles in the 1800s.
He formulated a mathematical equation that describes the relationship between the mass of a gas molecule and its rate of effusion.
This relationship is a
law because it describes what happens without explaining why.
law because it is based on mathematics.
theory because it describes a relationship.
theory because it is a description without an explanation.
This is because an equation does not explain why, which is a characteristic of a law. But, not all laws are based on mathematics. For example Newtons Laws of motion is simply statements.
law because it describes what happens without explaining why.
Law is something which does not give explanation why? It simply a law. It is not necessary that all laws are mathematical or should be expressed by equation.
