Date lllame Class l�oyle's Law According to Boyle's law, tile product of the pressure (P) and volume (V)-of a fixed mass of gas at constant temperature is a COIUltw\t (K). The following table contains pairs of pressure and volume readings °for • • • a. gas under such conditions.. For each pair of readings, multiply P x v to find the value of K. • I<'.- Pressure (kPa) Volume can•) {11Pa ,.· cm') 1. 20.0 60.0 � 1. 2. 30.0 40.0 _?_ 2: 3. 40.0. 30.0 1 3. 4. 60.0 • 20.0 _?_ 4. 5. 100.0 12.0 1 -- 5. 6. 200.0 6.00 _J_ 6. 7. 300.0 4.00 1 7. 8. 400.0 3.00 __ ?_ 8.
