Question

what is the ideal gas law?
a. a law comparing reactivities of different gases
b. a law predicting the freezing and boiling points of gases
c. a law describing the behavior of condensed gases
d. a law describing the properties of a gas

Explanation:

The ideal gas law, $PV = nRT$, relates the pressure ($P$), volume ($V$), amount of substance ($n$), and temperature ($T$) of an ideal gas. It describes the properties of a gas under ideal - conditions. It does not compare reactivities, predict freezing/boiling points, or describe condensed gases.

Answer:

D. A law describing the properties of a gas
