The Silicon chip (k = 149.0 W/(m-K) is 0.200 mm thick, and has dimensions of 25.0mm by 25.0mm. The pure aluminum plate is 0.850cm thick, and has the same dimensions as the Silicon chip. The hot side of the silicon chip is measured to be 62.0°C; the cold side of the pure aluminum plate is measured to be 31.0°C. Assuming steady-state conduction (with the thin layer of epoxy acting as contact resistance, see Table 3.2.) determine the heat transfer rate through the chip. Do not add in an addition resistance due to the thickness of the epoxy layer, this has been incorporated into the contact resistance.arrow_forward

- (a) Using data from the previous problem, find the mass of nitrogen, oxygen, and argon in 1 mol of dry air. The molar mass of N2 is 28.0 g/mol, that of O2 is 32.0 g/mol, and that of argon is 39.9 g/mol. (b) Dry air is mixed with pentane 5 H12, molar mass 72.2 g/mol), an important constituent of gasoline, in an air-fuel ratio of 15:1 by mass (roughly typical for car engines). Find the partial pressure of pentane in this mixture at an overall pressure of 1.00 atm.arrow_forwardThere is relatively little empty space between atoms in solids and liquids, so that the average density of an atom is about the same as matter on a macroscopic scale—approximately 103 kg/m3 .
