You have performed an activity in the laboratory to demonstrate how the thermodynamic variables such as Pressure, Volume and Temperature of a gas in an enclosure are
interdependent. Based on the data you have collected in your laboratory session, you are expected to present a report as per the guidelines given below.
• Briefly give a write up of the experiment demonstrated earlier. Your report should contain the aim with the procedure of the experiment.
• Tabulate your reading neatly in a column with proper units. Do necessary calculations, if needed.
• Plot a hand drawn graph between volume and pressure. Pressure should be on x-axis and volume on the y-axis. From the graph record the pressure in N/m2 when
volume is 20 ml. of air.
• A scanned copy of the observation sheet used in the lab and the graph must be attached along with your report.
• Assume that the cylinder contains Hydrogen gas at the above volume and pressure. Calculate the number of moles of Hydrogen gas using ideal gas law equation.
