What are the variables of Boyle’s law?

volume and number of molecules of gas
volume and temperature
pressure and temperature
pressure and number of molecules of gas
pressure and volume


  1. Answer: pressure and volume


    Boyle’s law states that the volume of a fixed mass of gas is inversely proportional to the pressure of the gas provided temperature is kept constant.

    Mathematically, Boyle’s law can be explained as: PV = k,

    where P is pressure

    V is volume, and

    k is a constant.

    So, increase in the pressure of a gas leads to decrease in its volume and vice versa.
