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 a constant for a particular mass and pressure of the gas. This law states at a constant pressure, the volume of a particular sample of gas is directly related to the temperature of the sample of gas. Procedure/Apparatus: In experiment one, an Erlenmeyer flask is taken from the shelf and placed on the work bench and closed. Then add 1.5 atm of methane gas to the flask and record that the initial volume of the gas and the initial pressure of the gas. Next take a syringe from the shelf and attach it to the flask and note that the syringe rises and the pressure goes from 1.5 atm to 1.0atm. Record the initial volume of the syringe and the volume of the flask to get the total volume. Then take a thermometer and attach it to the flask and
