Pressure and volume of gases
Author : Abel Carenas Velamazán
Boyle ' s law is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases . A modern statement of Boyle ' s law is :
“ The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and the quantity of gas remain unchanged within a closed system ”
