Question

Lesson Question: What is the effect of
on the volume of a gas?

Answer 1

I think part of your question got left out — which quantity are you asking about (pressure, temperature, amount of gas, etc.)? I’ll give the short, general answer and the common special cases.

General relation (ideal gas law):
V = nRT / P

So:
- If temperature T increases (with P and n held constant), volume V increases proportionally (Charles’s law).
- If pressure P increases (with T and n held constant), volume V decreases inversely (Boyle’s law).
- If amount n (moles) increases (with P and T held constant), volume V increases proportionally (Avogadro’s law).

Examples:
- Double T (in kelvin) → V doubles (if P and n constant).
- Double P → V halves (if T and n constant).
- Double n → V doubles (if P and T constant).

If you tell me which variable you meant, I’ll give a focused explanation or an example.
