- The ratio of the sine of an angle of incidence to the sine of the angle of refraction is a constant.
- The amount of energy generated from a chemical reaction is the same whether the reaction happens in one step or several steps.
- The force between two electric charges is inversely proportional
to the square of the distance between them and directly proportional to the product of their charges

4 True/False questions
Ohm → The amount of energy generated from a chemical reaction is the same whether the reaction happens in one step or several steps.
Boyle → The volume of a gas is inversely proportional to its pressure if temperature is held constant
Dalton → The total pressure of a gas mixture is equal to the sum of the partial pressures of the components
Graham → Electric current is equal to the potential difference across the conductor divided by resistance (I=v/R)
