Study Notes
Boyle's Law
- In 1662, Robert Boyle discovered the inverse relationship between gas volume and pressure, maintaining constant temperature.
- The relationship is mathematically represented as ( V \propto \frac{1}{P} ).
- Volume (V) decreases when pressure (P) increases, and vice versa.
- Expressed as ( V = \frac{k}{P} ), where k is the proportionality constant specific to the gas.
- The product of pressure and volume remains constant for a given mass of gas at a constant temperature: ( P_1V_1 = P_2V_2 ).
- Variables associated with Boyle's Law:
- ( P_1 ): Initial pressure
- ( V_1 ): Initial volume
- ( P_2 ): Final pressure
- ( V_2 ): Final volume
Experimental Verification of Boyle's Law
- Boyle's Law can be experimentally verified using a gas in a cylinder with a movable piston.
- At 2 atm pressure, the volume of gas recorded is 1 ( dm^3 ).
- Increasing pressure to 4 atm results in a volume reduction to 0.5 ( dm^3 ).
- At 6 atm of pressure, the volume decreases further to 0.33 ( dm^3 ).
- At 8 atm, volume is 0.25 ( dm^3 ).
- The experiments confirm that increasing pressure leads to a decrease in gas volume at a constant temperature, validating Boyle's Law.
