Experiment Charles Law

To find the relationship between volume and temperature at constant pressure

Procedure 1. Arrang Arrangee the appar apparatu atuss as shown shown in in the diagr diagram am 2. Fill the the beaker with with tap water water until until the air column column in the the capillary capillary tube tube is totally totally immersed in it. 3. Stir the the water and and record the the initial initial temperat temperature ure and the length length of the the air column column o as θ  C and l  cm respectively 4. Heat the the water water and stir it continuou continuously. sly. When the the temperatu temperature re increases increases by 10oC, remove the Bunsen burner and continue to stir stir the water. Record the temperature and length of air column in the capillary tube 5. Repeat procedur proceduree 4, recording recording the temperat temperature ure and the length length of air air column in in the o capillary tube for every increment of 10 C until the temperature of the water is near to its boiling point

Inference The volume of a fixed mass of gas depends on its temperature when its pressure is kept constant Hypothesis The higher the temperature, the larger the volume of a fixed mass of gas when the  pressure is kept constant Aim To investigate the relationship between the volume of a fixed mass of gas and its temperature when its pressure is constant Variables a) Manipulated : b) Responding : c) Fixed :
