## Chemistry: The Molecular Science (5th Edition)

The three laws are Boyle's Law, Charles's Law, and Avogradro's Law. The first states that pressure times volume is constant. The second states that Volume over temperature is constant. The third states that volume over the number of moles is constant. In math, this is: $PV = k$; $\frac{V}{T}=c$; and $\frac{V}{n}=a$, where k, c, and a are all constants.
