When technologists explore for oil deposits, they pass sound waves through sedimentary rock to determine the thickness of the layers. As the sound waves travel from one sedimentary layer to another, their paths are bent. This phenomenon is similar to the

Ideal Gas Law

Ideal gas law states that the product of pressure and volume of a gas directly varies with the product of the number of moles, the universal gas constant, and the temperature of the gas.
