what happens to the molar volume when the temperature increases?\nmolar volume increases\nmolar volume decreases\nmolar volume stays the same
Answer
Answer:
Molar volume increases
Explanation:
Step1: Recall ideal gas law
$PV = nRT$
Step2: Define molar volume
$V_m=\frac{V}{n}$, so $V = nV_m$. Substitute into ideal - gas law: $PV_m=RT$.
Step3: Analyze relationship
When pressure $P$ is constant, $V_m$ is directly proportional to $T$ (since $R$ is a constant). So as $T$ increases, $V_m$ increases.
