Exam-style question
Try this first
When the temperature of a gas increases, what happens to its pressure if the volume remains constant? Explain your reasoning.
Model answer
What a good answer should say
- If the temperature of a gas increases while the volume remains constant, the pressure of the gas also increases.
- This is because the kinetic energy of the gas molecules increases, leading to more frequent and forceful collisions with the walls of the container.
Explanation
Why this works
This response accurately describes the direct relationship between temperature and pressure as outlined by Gay-Lussac's Law. The implication is that increasing temperature results in increased pressure, which is crucial for understanding gas behavior in fixed volumes.
The conclusion reinforces the importance of temperature in determining gas pressure.
