A thin-film gold conductor for an integrated circuit in a satellite application is deposited from a vapor, and the deposited gold thin film has a high resistivity. It is proposed that the high resistivity is due to a high non-equilibrium vacancy concentration, created when the vapor atoms rapidly condense into the thin film. To reduce the vacancy concentration, it is proposed to anneal (heat) the gold to a temperature that will result in only 1 vacancy for every 108 gold atoms, and then to cool the film slowly to room temperature. The enthalpy of formation for 1 vacancy in gold is equal to 0.94 eV. Specify the temperature

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
