Adding Helium to an expanding reflective plastic film balloon. (Most people
would just call this a Mylar balloon) The pressure remains constant as the gas is added and the
volume of the balloon increases. The temperature remains constant.
On pages 4-44, the scenario is presented. Sketch the Macro/Micro Chart and fill it in showing
which properties are increasing (↑), decreasing (↓), or remaining the same (↔). Remember
that the average speed and the average kinetic energy change the same way. This chart does
not contain the average kinetic energy.
