For many purposes we can treat butane (C4H10) as an ideal gas at temperatures above its boiling point of 1. C Suppose the pressure on a 640.mL sample of butane gas at 15.0C is cut in half. \begin{tabular}{|l|l|} \hline Isitpossibletochangethetemperatureofthebutaneatthesametimesuchthatthevolumeofthegasdoesntchange? & yes \\ \hline Ifyouansweredyes,calculatethenewtemperatureofthegas.RoundyouranswertothenearestC. & C \\ \hline \end{tabular}
