Gas laws Study guides, Class notes & Summaries

Experiment #: 5 Title: Gas Laws Purpose: The study of gasses, their laws, and how they affect atmospheric pressure. Procedure: We are going to be looking at a tool where we can demonstrate Boyle’s law with a syringe fitted in a base and it is capped off with a wooden base and platform where we are going to place weights. We are going to be looking at pounds per square inch and right now it is about 14.3. If we look at our plunger without any weight on top the atmospheric pressure is abou...

CHEM120 Week 4 Concepts: The Ideal Gas Laws and Acid/Base Reactions- Download To Score An A+ PHYSICAL STATES OF MATTER In this section, we will discuss the Ideal Gas Laws. First, we will review the properties of solids, liquids, and gases. Second, we will discuss the kinetic-molecular theory of gases, which explains why they are so unique compared to other states of matter. Finally, we will discuss gas law equations, and practice using them to solve for different parameters. This unit has many s...
