An air bubble of volume 1.0 cm^(3) rises...

An air bubble of volume `1.0 cm^(3)` rises from the bottom of a lake 40 m deep at a temperature of `12^(@) C`. To what volume does it grow when it reaches the surface, which is at a temperature of `35^(@) C`. ? Given `1 atm = 1.01 xx 10^(5) Pa`.

Text Solution

Verified by Experts

`V_(1)=10^(-6)m^(3)`
Pressure on hubble `P_(1)=` Water pressure `+` Atmospheric pressure
`=pgh+Patm`
`=4.93xx10^(5)Pa`
`T_(1)=285k`, `T_(2)=308k`
`(P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2))`
`V_(2)=(4.93xx10^(5)xx1xx10^(-6)xx308)/(285xx1.01xx10^(5))=5.3xx10^(-6)m^(3)`.

    A small bubble rises from the bottom of a lake, where the temperature and pressure are 8^(@) C and 6.4 atm , to the surface of the water , where the temperature is 25^(@) C and pressure is 1.0 atm . Calculate the final volume ("in mL") of the bubble if its initial volume was 2.1 mL . Strategy : The amount of gas in the bubble remains constant (n_(1) = n_(2)) but there is a change in all the three quantities p , V , and T . This suggests that we use the combined gas law. We tabulate what is known and what is asked for , solve the combined gas law for the unknown quantity V_(2) and substitute the known values.
