Derive an equation for the work of mechanically reversible, isothermal compression of 1 mol of a gas from an initial pressure P1 to a final pressure P2 when the equation of state is the virial expansion [Eq. (3.33)] truncated to: Z = 1 + B′P How does the result compare with the corresponding equation for an ideal gas?

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
