For many purposes we can treat ammania (NH3) as an ideal gas at temperatures above its boiling point of 33.C. Suppose the temperature of a sample of ammonia gas is raised from 31.0C to 46.0C, and at the same time the pressure is increased by 10.0%. \begin{tabular}{|l|l|} \hline Does the volume of the sample increase, decrease, or stay the same? & Increase \\ \hline & decrease \\ \hline \end{tabular}
