Homework Statement At 25C Cu metal (at. wt. 63.54 g/mol) has a molar heat capacity of 24.4 J/molK. The density of Cu is 8.949g/cm^3 at 0C and 8.904 g/cm^3 at 100C. Assuming that Cp is temperature independent, calculate Q, W, deltaU and deltaH when 100grams of Cu metal are heated from 0C to...

Homework Statement The variation: deltau = (6x^2y+3lny)dx + (2x^3+3x/y)dy is an exact differential and u is given by u = 2x^3y+3xlny Demonstrate by integrating deltau along the two different paths from point A(1,1) to point B(3,2) (one path has a constant y from x=1 to x=3 and then the x...
