Gases are for the most part invisible, and therefore cannot be observed as readily as a solid or a liquid. Because of this, they are often examined and analyzed through measurable physical characteristics such as volume, pressure, temperature, and moles (number of particles). These properties have simple, consistent mathematical relationships that led to the development of the gas laws (Boyle’s, Charles’s, and Gay-Lussac’s), and eventually the ideal gas law. By using these relationships you can determine the value of an unknown property based on the other three, or predict the effect that varying one component will have on the others. In this activity, students will use the Innovating Science apparatuses and your temperature and pressure sensors to measure and plot the physical characteristics of a gas. Kit contains an Instruction Manual and enough materials for 2 groups of students.
