5.3.129 - Absolute zero and molecular kinetic energy

Syllabus
2021
Objective
5.3.129
Level
A2

- Absolute zero and molecular kinetic energy

Understand the concept of absolute zero and how the average kinetic energy of molecules is related to the absolute temperature.

Use - absolute zero and molecular kinetic energy to connect the rule to the data and decision in the question.

This matters because - absolute zero and molecular kinetic energy determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - absolute zero and molecular kinetic energy to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Absolute zero and molecular kinetic energy is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
