Q3. Boyle's Law and Gas Behavior

Background

Topic: Gas Laws (Boyle's Law)

This question tests your understanding of Boyle's Law, which describes the relationship between the pressure and volume of a gas at constant temperature and amount of gas. You are asked to interpret a graph and identify which statements about Boyle's Law are correct.

Key Terms and Formulas:

• Boyle's Law: (at constant temperature and amount of gas)

• Inverse Proportionality: As pressure increases, volume decreases, and vice versa, when temperature and amount of gas are constant.

Step-by-Step Guidance

1. Examine the graph provided. Notice how the volume changes as the pressure increases. Is the relationship direct or inverse?

   

2. Recall that an inverse relationship means that as one variable increases, the other decreases. Does the graph show this behavior?

3. Consider the statements given in the question. Which ones correctly describe the relationship shown in the graph?

4. Think about whether Boyle's Law was used to derive the Kelvin temperature scale, or if it only describes pressure-volume relationships.
