The ideal gas law The ideal gas law states that the volume $V$ that a gas occupies is directly proportional to the product of the number $n$ of moles of gas and the temperature $T$
(in K) and is inversely proportional to the pressure $P$ (in atmospheres).
(a) Express $V$ in terms of $n, T, P,$ and a constant of proportionality $k$
What is the effect on the volume if the number of moles is doubled and both the temperature and the pressure are reduced by a factor of one-half?
