[quote=alza3eem;1498726]A small bubble rises from the bottom of a lake, where the temperature and pressure are 4°C and 3.0 atm, to the water's surface, where the temperature is 25°C and the pressure is 0.95 atm. Calculate the final volume of the bubble if its initial volume was 2.1 mL.




A. 0.72 mL
B. 6.2 mL
C. 41.4 mL
D. 22.4 mL
E. 7.1 mL


p1 = 3
p2 = 0.95
t1 = 277
t2 = 298
v1 = 2.1
v2 = ?

3*2.1/277=0.95*?/298

0.0227436823104693 = 0.0031879194630872 v2

0.0031879194630872 * 0.0227436823104693 = v2

v2 = 7.250502749981824e-5
