5.3.130 - Ideal gas equation

Be able to use the equation pV = NkT for an ideal gas.

Use - ideal gas equation to connect the rule to the data and decision in the question.

This matters because - ideal gas equation determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - ideal gas equation to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
