Name: Date: Boyle’s La The relationship between the volume of a gas and the pressure of a gas, at a constant temperature, is known as Boyle 's law. The equation for Boyle's law is at right . BOYLE’S LAW Initial volume New pressure — Initial pressure * Units for pressure include: atmospheres ( atm ), pascals ( Pa ), or kilopascals ( kPa ). Units for volume include: cubic centimeters ( cm 3 ), cubic meters ( m 3), or liters.
