Question
Give reason for the following:
Temperature remaining constant the product of the vol. & the press, of a given mass of dry gas is a constant.

Solution
According to Boyle's Law V α `1/"p"`
V = K.`1/"p"`
∴ P × V = K = a constant
∴ Product of volume and pressure of a given mass of dry gas is constant. [at constant temperature]
