Properties of Matter Part 2

An air bubble of volume 1cm3 rises from the bottom of a lake 40m deep to the surface at a temperature of 12∘C. The atmospheric pressure is 1×105‌Pa, the density of water is 1000‌kg∕m3 and g=10m∕ s2. There is no difference of the temperature of water at the depth of 40m and on the surface. The volume of air bubble when it reaches the surface will be:
