Investigating the relationship between pressure, volume and temperature of a gas

... Title Investigating the relationship between pressure, volume and temperature of a gas Objective - To investigate, for a fixed amount of gas, the relationship between * volume and temperature at constant pressure, i.e. Charles's law * pressure and temperature at constant volume, i.e. Pressure law * pressure and volume at constant temperature, i.e. Boyle's law Apparatus Capillary tube (with silver thread) x1 Thermometer x1 500 mL round-bottomed flask x1 Bourdon gauge x1 100 mL syringe x1 Hot plate with magnetic stirrer x1 2500 mL beaker x1 Jack x1 Theory Thermal behavior of gases is often described by sets of relationship among the common macroscopic quantities such as pressure P, volume V, temperature T and mass m. In this experiment, fixed amount of air is used as the gas for investigation. Since only two variables should be changed at one time, consequently there are three relationships to be explored: (I) V-T at constant P, (II) P-T at constant V, and (III) P-V at constant T. (I) V-T at constant P To
