A small bubble rises from the bottom of a lake, where the temperature and pressure are `8^(@)C` and `6.0 atm`, to the water's surface, where the temperature is `25^(@)C` and pressure is `1.0 atm`. Calculate the final volume of the bubble if its initial volume was `2mL`.

Options

A. 14 mL
B. 12.72 mL
C. 11.31 mL
D. 15 mL

Answer

b

Explanation

(b) The moles of the gas in the bubble remains constant, so that `n_(1)=n_(2)`. To calculate the final volume, `V_(2),`
`V_(2)=V_(1)xx(P_(1))/(P_(2))xx (T_(2))/(T_(1))`
` =2.0 mLxx(6.0 atm)/(1.0 atm)xx(298 K)/(281K)`
`=12.72 mL`
