Advanced Gas Laws Demo

Quantitatively confirm the Combined Gas Law with one complete apparatus! The Combined Gas Law simplifies the Ideal Gas Law and describes a relationship between the pressure, temperature and volume of a gas that is constant. Students can verify this relationship using air and this unique apparatus. Twist the handle to compress the air, and simply read the volume, temperature and pressure from the scales. Repeat and show that the relationship stays the same. Please note: 1 AA battery is required for the temperature gauge and is not included.
