A small bubble rises from the bottom a lake, where the temperature and pressure are 4 deg C and 3.0 atm, to the waters surface, where the 25°C and 95 atm. How do you calculate the final volume of the bubble if its initial volume was 2.1 mL?

I think you might want to review this question's terms. I get approx. 7*mL IF the end pressure is 0.95*atm.

Explanation:

We use the "combined gas law:" (P_1V_1)/T_1=(P_2V_2)/T_2.

And thus V_2=(P_1xxV_1xxT_2)/(T_1xxP_2)

=(3.0*atmxx2.1*mLxx298*K)/(277*Kxx0.95*atm)=??mL
