Item 9 9 of 16 > Part A - Organize the data Since volume and pressure are inversely related, we can make some assumptions about initial and final states using the data provided. We can also identify initial and final states by finding trigger words in the language of the problem. Look for words like "first," "initially," or "originally" to describe initial states and "result" or "after" for final states. What volume would a sample of helium occupy at 6.0 atm if the helium was initially compressed in a 1.0 L tank at 20. atm at constant temperature? Organize your data into the table to help analyze the problem. Leave blank any boxes for which you do not have information. Drag the appropriate labels to their respective targets. • View Available Hint(s) Reset Help V V 100 20. 6.0 2.0 1.0 P increases increases decreases decreases Analyze the problem Initial conditions Final conditions Know Predict Pressure Group 1 atm Group 1 atm Group 2 Volume Group 1 L Group 2

Item 9 9 of 16 I Review I Constants I Periodic Table Learning Goal: Develop problem-solving skills using pressure-volume relationships and Boyle's Law. Solving problems with gas laws You can solve many gas-law problems using these basic problem-solving steps: 1. Organize the data for initial and final conditions. You may want to use a table. 2. Rearrange the gas law equation to solve for any unknown quantities. 3. Substitute values into the gas law equation and then calculate. Manipulating gas laws Unlike liquids and solids, gases completely fill any container they are placed in and the collisions of gas molecules with the container walls lead to a pressure exerted on the container. Boyle's Law describes the relationship between the pressure P and the volume V of a gas when temperature is constant. Boyle observed that when the volume of a container of gas is increased, the pressure decreases; similarly when the volume is decreased, the pressure is increases. These observations can be written mathematically as PVi = P2V2 where the subscripts 1 and 2 are used to denote, respectively, the initial and final states of the system. The relationship between the pressure and volume of a sample of gas has many profound, practical implications. Boyle's Law helps to describe everything from balloons to breathing, from soda cans to syringes. The goal of this tutorial is to help you become comfortable with problem-solving methods that you can apply to a variety of problems in this course. You will learn to organize the data given in the problem, rearrange equations to solve for an unknown, and substitute values into the equation to calculate a numerical answer. It is essential that you work through and understand all three parts of this method; the most common mistakes are made by students who try to skip straight to calculating a number without giving appropriate attention to organizing their data and setting up the correct equation.
