# Grade 10 Science Module: Boyle’s Law

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

How can you relate pressure and volume in real life situation? Generally, you fill a car tire with compressed air pressure ranging from 30 to 35 psi. The psi (pounds per square inch) is a unit of measurement for pressure. As you put more and more air into the tire, you are forcing all the gas molecules to get packed together, reducing their volume and increasing the pressure pushing on the walls of the tire. As long as the air temperature remains the same, you are experiencing a real-life example of volume and pressure relationship.

This module will provide you with information and simple activities to help you understand volume and pressure relationships at constant temperature.

After going through this module, you are expected to:

1. investigate the relationship between volume and pressure at constant temperature of a gas;

2. solve problems involving changes in the condition of the gas using the equation for Boyle’s Law; and

3. give application of Boyle’s Law in real life situations.

Going through this module can be a meaningful learning experience. All you need to do is make use of your time and resources efficiently.
