The Physics Of The Gas - 1023 Words

Charles’ Law Introduction: Charles’ Law states that if a given quantity of gas is held at a constant pressure, its volume is directly proportional to the temperature. The purpose of this lab is to demonstrate that when the gases are heated the volume of the gas will expand and increase the total volume. The gases when heated made the syringe rise and therefore expanding the volume potential of the gases. Theory: According to Charles Law the volume of a gas is directly proportional to the Kelvin temperature assuming the pressure is constant. Charles’ Law when relating the volume of a gas at constant pressure to its temperature is summarized in this formula: V/T = k where T is the temperature (in degrees Kelvin), V is the volume and k is†¦show more content†¦After recording all data in the lab notes, take a constant temperature bath from the shelf and place it on the work bench, adjust the temperature of the constant temperature bath to 0 degrees Celsius. After that place the flask in the constant bath, let the temperature reach a constant point and then record the new data. After that change the temperature of the constant temperature bath to 40 degrees Celsius, allow the temperature to stabilize and record the new volume and temperature of the gas. Next change the temperature of the constant temperature bath to 60 degrees Celsius, 80 degrees Celsius, and 100 degrees Celsius and record the temperature in Kelvin and the new volume at all of the temperatures listed above. Then clear the work bench and prepare for the next experiment. In experiment number two, take an Erlenmeyer flask form the shelf and place it on the workbench and close it. Then add 1.5atm of butane gas to the flask and note that the volume of the flask is 150mL (the gas occupies the entire volume of the flask.) Next take a syringe from the materials shelf and place it in the flask and record the new volume of both the flask and the syringe. After recording the data in the lab notes take the flask and place it in a constant temperature bath at 40 degrees Celsius. Record the temperature (in degrees Kelvin) and the volume of the flask added to the volume of the syringe in the lab notes. Next change the temperature of the
