Aim a) To verify that the pressure of a gas varies linearly with its temperature (expressed in degrees Celsius) when the volume of the gas is kept constant. b) To make an estimate in degree Celsius of absolute zero.
As more force on the area,the pressure increase. According to the Pressure law,for constant volume and mass of a gas,the pressure exerted on the side of the container is directly proportional to the absolute temperature(in Kelvin) of the gas.Thus, the temperature would reach absolute zero as pressure become zero. We can determine absolute zero by extrapolating the pressure vs. temperature graph to zero pressure. Variable Variable Method of measuring Independent Variable Temperature We determine the temperature of the gas by measuring the temperature of the water.
