Which proportionality applies to Avogadro's law?
Avogadro's law is a fundamental principle in chemistry that relates the volume of a gas to the amount of substance (number of moles) of that gas. The law states that, under constant temperature and pressure conditions, the volume \(V\) of a gas is directly proportional to the quantity of gas, expressed in moles \(n\). This can be mathematically represented as \(V \propto n\), or \(V = kn\) for some constant \(k\).
We evaluate the given options to identify which one corresponds to Avogadro's law:
Based on the definitions of the gas laws, the proportionality \(V \propto n\) is the correct representation of Avogadro's Law. Therefore, the final answer is \(V \propto n\).
Imagine you are inflating a balloon for a party. According to Avogadro's Law, as you breathe more air (more moles of gas molecules, \(n\)) into the balloon while the pressure and temperature remain relatively constant, the balloon expands to a larger volume (\(V\)). This direct relationship explains why adding more gas molecules consistently results in an increase in the volume occupied by the gas.
