An air bubble starts rising from the bottom of a lake and its radius is doubled on reaching the surface. If the temperature is costant the depth of the lake is. ( 1 atmospheric pressure = 10m height of water column)

What will happen to volume of a bubble of air found under water in a lake where temperature is 15^(@)C and the pressure is 1.5 atm, if the bubble rises to the surface where the temperature is 25^(@)C and the pressure is 1.0 atm?

What will happen to the volume of a bubble of air found under water in a lake, where the temperature is 15^(@)C and the pressure is 1.5 atm. If the bubble then rises to the surface where the temperature is 25^(@)C and the pressure is 1.0 atm ?

An air bubble of 20 cm^3 volume is at the bottom of a lake 40 m deep where the temperature is 4^@ C . The bubble rises to the surface which is at a temperature of 20 ^@ C . Take the temperature to be the same as that of the surrounding water and find its volume just before it reaches the surface.
