Boyle's law is also known by other names like Boyle- Marriotte law or Marriotte's law.
After watching the Boyle's law animation you will understand the relationship between pressure and volume of an ideal gas when temperature and number of molecules (mass) of the gas are kept constant. The concept lying behind the Boyle's law has been explained in this simulation of Boyle's law.
What is Boyle's Law (Definition of Boyle's Law)
According to Boyle's law the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
