A small bubble rises from the bottom of a lake, where the temperature and pressure are 8°C and 6.4 atm, to the water’s surface, where the temperature is 25°C and the pressure is 1.0 atm. Calculate the final volume (in mL) of the bubble if its initial volume was 2.1 mL.

*Strategy* In solving this kind of problem where a lot of information is provided, it is often helpful to organize the information. The given information is tabulated here:

\begin{matrix} Initial Conditions & & Final Conditions\\\hline \\ P_{1}=6.4 amt & & P_{2}=1.0 atm \\ V_{1}=2.1 mL & & V_{2}=? \\T_{1}=(8+273) K=281 K & &T_{2}=(25+273) K=298 K\end{matrix}

What temperature unit should be used in the calculation?
