Exam-style question
Try this first
A gas is compressed in a piston, causing its pressure to increase while the volume decreases. Explain the relationship between pressure and volume in this scenario.
Model answer
What a good answer should say
- The pressure of a gas increases as its volume decreases, which is described by Boyle's Law.
- This relationship indicates that for a given amount of gas at constant temperature, the product of pressure and volume remains constant.
Explanation
Why this works
This answer demonstrates an understanding of Boyle's Law, which is a key concept in gas behavior. It shows that the pressure-volume relationship is inversely proportional, implying that compressing a gas increases its pressure.
This conclusion is essential for understanding how gases behave under varying conditions.
