A scuba diver releases spherical air bubble of diameter 3 cm, from a depth of 14 m. Assume the temperature is constant at 25oC and that the air inside the bubble behaves as an ideal gas. Find the heat added or removed from the air as it rises.

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
