Temperature Difference and Heat Transfer

Whenever there is a flow of heat flux resulting from a temperature gradient within the material or between two materials, there is heat transfer. Heat transfer primarily arises due to temperature differences between two bodies or within bodies. The term temperature gradient denotes temperature differences or variation of temperature due to change in some quantity. The fundamental use of the concept of temperature is found in the zeroth law of thermodynamics.

Fluid Mechanics Last Fall, researchers using an unmanned submarine discovered a coral reef at the unprecenented depth of 1/2 mile. The density of seawater at the surface of the ocean is 1025kg/m3 and the bulk modulus of elasticty of seawater is 2.34*109 Pa. A volume of air is taken downward to the coral reef. Assuming an absolute air pressure at the ocean surface of 1 atm, and that the air taken to the reef behaves as an isothermal gas. Find the pressure of the air at that depth. Find the fractional change in denisity and volume of the air at that depth.
