Rank the magnitudes of the diffusion coefficients from greatest to least for the following systems: (a) Cr in Fe at 600°C; (b) C in Fe at 900°C; (c) Cr in Fe at 900°C. Now justify this ranking.

Which of the following is the correct definition of mechanical energy?

At steady state, a refrigerator whose coefficient of performance is 3 removes energy by heat transfer from a freezer compartment at 0 degrees C at the rate of 6000 kJ/hr and discharges energy by heat transfer to the surroundings, which are at 20
