In the study of the vapour pressure of chloroform is determined. Chloroform is placed in a container and allowed to reach a temperature op 28C. A vacuum is then created at which point the chloroform start to boil. The pressure and temperature are recorded. Subsequently the vacuum is gradually reduced by allowing a small amount of air into the vessel, thereby increasing the pressure in the vessel. At each of these higher pressures, the solution is heated and till it boils again and the temperature point and pressure is recorded at which the solution boils. This is repeated until the vessel reaches room pressure. What is the dependent and independent variable?
