Charles's (Amontons') law (with the Cobra3 Basic-Unit)

 Product No: P3011211

Principle

The state of a gas is determined by temperature, pressure and amount of substance. For the limiting case of ideal gases, these state variables are linked via the ideal gas law. For a change of state under isochoric conditions this equation becomes Amontons' law.

Tasks

  1. Experimentally investigate whether Amontons' law is valid for a constant amount of gas (air)
  2. From the resulting relationship calculate the universal gas constant and thermal coefficient of tension.

What you can learn about
