Question

question 14
which of the following laws states that the volume of a gas is directly proportional to kelvin temperature at constant pressure (and the number of gas moles constant)?
charles law
boyles law
daltons law
gay - lussacs law
avogadros law

Explanation:

• Charles' Law: \( V \propto T\) (at constant \( P\) and \( n\)), where \( V\) is volume, \( T\) is Kelvin temperature, \( P\) is pressure, and \( n\) is the number of moles.
• Boyle's Law: \( P \propto \frac{1}{V}\) (at constant \( T\) and \( n\)).
• Dalton's Law: \( P_{total}=P_1 + P_2+\cdots\) (partial pressures of gases in a mixture).
• Gay - Lussac's Law: \( P\propto T\) (at constant \( V\) and \( n\)).
• Avogadro's Law: \( V\propto n\) (at constant \( T\) and \( P\)).

Answer:

Charles' Law
