1.4.26 - Core Practical 2 - viscosity by falling-ball method

CORE PRACTICAL 2: Use a falling-ball method to determine the viscosity of a liquid.

Use - core practical 2 - viscosity by falling-ball method to connect the rule to the data and decision in the question.

This matters because - core practical 2 - viscosity by falling-ball method determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - core practical 2 - viscosity by falling-ball method to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Core Practical 2 - viscosity by falling-ball method is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
