WHAT IS THE RELEVANCE
OF HENRY'S LAW TO LAW ENFORCEMENT
OFFICERS IN THE FIELD?

It helps in testing if a person is drink- driving which is a serious offense.

Explanation:

The scientific principle “Henry’s Law,” was named after the chemist William Henry in 1803.

It is used to determine if a person is drink driving and is the simplest and most cost-effective just by using the breath test.

Henry's Law predicts that if a volatile substance such as alcohol is dissolved in some solvent such as blood the concentration of the alcohol in the vapor above the liquid (i.e. your breath) will be proportional to its concentration in the blood. Henry's Law requires a closed system where there is a constant pressure and a constant temperature.
