In this lesson, we use a bladder-like air shoe to illustrate the concept of the bulk modulus. Hydrostatic fluid elements are used to model the air and the ideal gas law describes the air's behavior. Check out the model and find out what the difference is with and without air when the same amount of pressure is applied to the shoe base.
