Label them hot, warm, cool, and cold, just to help you keep track. This happens because the air inside the balloon, which is a gas, takes up a smaller volume when it is cool, and takes up a larger volume when it is heated. WHY THIS HAPPENS:-. 0000015417 00000 n Boyle's Law relates to volume and pressure. This method works best for a purely visual demonstration. What are the possible sources of error in your experiment? I got an A due to this amazing. When this data is graphed, the result is a straight line, indicative of a direct relationship, shown in the figure below. This relationship allows changes in the volume of a fixed mass * of gas to be calculated given a change in temperature. In a syringe, the volume of a fixed amount of gas is increased by drawing the handle back, thereby lessening the pressure. This means the temperature of the gas and liquid inside the syringe is the same as the temperature of the water in the beaker. The observation table is as follows: As Charles's law states the ratio of volume to temperature remains constant for fixed amount of gas at a constant pressure. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.
