Predict the volume Vf of the gas at pressure Pf of 425 kPa using the equation for Boyle's Law. Then predict the volume of the gas at 425 kPa using the graph in your book titled "Volume v. Pressure for a Fixed Amount of Gas at Constant Temperature." Compare the two predictions.

Solve Equation PiVi = PfVf (225 kPa)(200 L) = (425 kPa)Vf

CONNECT IT You can combine the proportional relationships of Boyle's Law

(PiVi PfVf), Charles's Law (Vi/Ti Vf/Tf), and the pressure-temperature relationship (Pi/Ti Pf/Tf), to get (PiVi)/Ti (PfVf)Tf. Explain in your own words how the combined laws could help you study.

Solids, Liquids, and Gases

You are about to work some magic with matter. You have a rectangular cube of matter in its solid state. It measures 3 in 4 in 5 in. You have available a rectangular container measuring 5 in 6 in 3 in. You also have a cylindrical container with base radius of 2.5 in and height 8 in. Illustrate how the matter "fits" in each container when it is in its solid, liquid, and gaseous states.

Solids, Liquids, and Gases Chapter Wrap-Up

Now that you have read the chapter, think about what you have learned and complete the table below.

1. Write an A if you agree with the statement. 2. Write a D if you disagree with the statement.

Solids, Liquids, and Gases

? Solid, liquid, and gaseous states of matter are determined only by temperature.

? Plasma is the most abundant state of matter in the universe.

? Earth's atmosphere is a fluid system.

After You Read

? Hydraulic lifts and squeezing toothpaste onto your toothbrush both apply Pascal's principle.

? Pressure and temperature are directly proportional properties of a gas.

Compare your previous answers to these.

Review
