Hi, I have a physics problem that I am not sure how I should be approaching: Consider a sample consisting of 10.0L of air at absolute pressure 2.00 atm, with density 2.40 kg/m^3. Find the work required to transport it to a depth of 10.3m with its temperature, volume, and pressure remaining constant. What should I be looking for in this question? My intuition tells me I should be looking for the change in energy as it changes depth. How should I be thinking about this question? Any helpful hints would be appreciated. Thanks in advance.
