• Select isotherm
• Keep T1 constant and measure the change in volume and pressure for all the available gases H2 , He, CO2 , N2, Xe, CCl4
• Name the file
• Keep T2 constant and measure the change in volume and pressure for all the available gases 
• Compare data and graphs
• Select isochor
• Name the file
• Keep V1 constant and measure the change in pressure and temperature for all the available gases 
• Keep V2 constant and measure the change in pressure and temperature for all the available gases 
• Compare data and graphs

Explain the main idea of the exercise and tell the students to record carefully the data in their notebooks. The main objective is measuring, on the same condition for different gases, the relationship between pressure and volume at constant temperature (isothermal law)  and the relationship between temperature and pressure at constant volume (isochoric law). The students will repeat the exercise with the following gases:  H2 hydrogen, He2 helium, N2 nitrogen, Xe xenon, CO2 carbon dioxide, ideal gas, CCl4 Carbon tetrachloride

4. Keep V1 constant and measure the changes in pressure and temperature for all the available gases  
5. Name the file
6. Keep V2 constant and measure the change in pressure and temperature for all the available gases  
7. Compare data and graphs
