COMBINED GAS LAW SUMMARY The combined gas law is a gas law which combines Charles's law, Boyle's law, and Gay-Lussac's law. This law states: “The ratio between the pressure-volume product divided by the temperature of a system remains constant.” This can be stated mathematically as:  Where: p is the pressure, V is the volume, T is the temperature measured in kelvins, and k is a constant (with units of energy divided by temperature). Reminder: 1atm= 760 torr = 101.3 kPa & Celsius to Kelvin=

Boyle's Law Examples in Real Life Boyle's Law Explained In 1662, Robert Boyle discovered that when held at a constant temperature, the volume and pressure of a gas are inversely proportionate. Put simply, when the volume goes up, pressure drops, and vice versa. The mathematic equation is equally as simple: PV=K where P=Pressure, V=Volume, and K is simply a constant. This has become a basic principle in chemistry, now called "Boyle's law" and is included as a special case into the more general

75 & 82. Gas Properties 1. 2. 3. 4. Gases are highly compressible where liquids and solids are not. Gases occupy full volume of the container. Gases always form homogenous mixtures. In gases, there is spaces between gaseous molecules. 5. 1 Pressure Pressure = Force - N Area – m2 in Pascals (SI units) Pressure is measured using pressure gauges or diaphragm gauges. Atmospheric Pressure at sea level is 1 atm = 760 mm = 760 torr = 1.01 x 105 Pascals 5.2 The Gas Laws of Boyle, Charles
