Experiment nº5: Practical use of Gay Luissac's law

Objective:
The aim of the experiment is to observe and understand how the pressure of a gas changes in relation with the temperature at which the gas is submerged.

Materials:

• Container
• Stand
• Clamp
• Bunsen Burner
• Wood pieces
• Tripod
• Schlenk
• Water
• Lighter
• Electronic thermometer
• Magnet
• Magnetic stirrer
• Manometer

Explanation of the relation between temperature and pressure. (Elisa Millán)

According to Gay-Lussac’s law, for a given amount of gas held at constant volume, the pressure is proportional to the absolute temperature. As we can see in the image above the relationship between volume(y) and temperature(x) is a directional proportion for a constant pressure but when volume is held constant we will find an inverse proportional relationship between pressure(y) and temperature (x). We can observe this relationship using the following formula:

P/T=K
