MODULE 3 UNIT 3 Experiment 2 CHARLES’ LAW The volume of a given sample of gas at constant pressure is directly proportional to the temperature in kelvins. In other words, gases tend to expand when heated. IMPORTANT DEFINITIONS Volume: amount of three-dimensional space occupied by a substance Temperature: measure of the random motions (average kinetic energy) of the components of a substance Pressure: force per unit area GO TO THIS WEBSITE What factors influence the pressure of a gas in a container? 1. Familiarize yourself with the animation. 2. There is a beaker containing a gas. It sits on a hotplate. A thermometer measures temperature in degrees Celsius. Click on the ‘Temperature’ button, above the thermometer. Now, you can adjust the temperature, by clicking on the buttons on the hotplate: LO = 60°C MED = 100°C HI = 140°C 3. A pressure gauge measures pressure in kPa (kilopascals). 4. There is a plunger in the beaker that can be adjusted to make different volumes. Click on the ‘Volume’ button, above the pressure gauge.
