Exam-style question
Try this first
Explain how an increase in temperature affects the pressure of a gas in a closed container, according to the ideal gas law.
Model answer
What a good answer should say
- An increase in temperature causes the kinetic energy of gas particles to increase, leading to more frequent and forceful collisions with the container walls.
- This results in an increase in pressure within the container.
Explanation
Why this works
This answer effectively follows the cause-effect reasoning pattern by identifying the increase in temperature as the cause, explaining the mechanism of increased kinetic energy and collisions, and stating the effect of increased pressure. It demonstrates an understanding of the ideal gas law and its implications.
