A fish swims to a depth of 50.00 meters in the ocean. Assuming the density of sea water is 1.025 g. cm3, calculate how much water pressure the fish is experiencing at this depth in units of kPa.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

Q9 Gas Expansion Efficiency
8 Points
3.00 moles of Ne gas irreversibly and isothermally expands from an initial volume of 4.00 L to a
final volume of 17.00 L at 25.0°C. Calculate the work (in kJ) for this expansion and compare it to
the maximum amountfof work that can be achieved (i.e. what is the efficiency).
