Explain the difference between a manometer and a barometer.

Write the proportional statement based on Graham's law of effusion that allows you to compare the diffusion rate of two different gases.

Which of the following is not an observed property of gases?

gases vary in shape and volume

gases expand infinitely

gases compress infinitely

gases have low density

gases mix completely

Describe the following concepts as they relate to the behaviors of gases by completing the passages below. $\mathbf{low \ density}$-Gases have low density (____ per ________), in comparison to ____. The difference in density is partly due to the mass of the _____ and also because there is a great deal of ____ between gas particles. $\mathbf{compression \ and \ expansion}$-The large amount of ______ between gas particles allows them to be ________, or pushed, into a ____ volume. Once the pressure is _______, the particles _____ to the original _____. $\mathbf{diffusion \ and \ effusion}$-Because there are no _____ forces of ____ between gas particles, gases _____ past one another. This ____ motion allows gases to mix until they are _______. The movement of ______ past one another is called ____. The process of allowing a gas to escape from a more concentrated container is called _____.

Describe kinetic energy in equation form by completing the table below.

$$\begin{array}{|l|l|l|} \hline K E=1 / 2 m v^{2} & \text { Variable } & \text { Definition } \\ \hline K E & & \\ \hline m & & \\ \hline \mathrm{v} & & \\ \hline \end{array}$$

Distinguish between the three main physical properties of gas particles by completing the passages below.

1. Size is very _____ . It is assumed that there are ____ significant _____ or ______ forces among gas particles.
2. Motion is _____ moving in a ____ pattern. It is assumed that gas particles move in a ____ path until they ______.
