Heat capacity of electrons and lattice atoms. (a) At which temperature do the lattice atoms and the electrons in gold contribute equally to the overall heat capacity. (b) In what limits could we: i. Ignore the electron contribution ii. Ignore the lattice contribution when calculating the overall heat capacity? Note: Although Debye temperature can vary somewhat with temperature, we will assume it is a constant value of θAu = 170K. (MAu = 170 g/mol, ρAu = 19.32 g/cm3); the concentration of conduction electrons in gold is N/V = 5.9×1022 cm−3

1. A meeting hall is to be maintained at 25 °C, 18 °Cwb. The space latent heat gain is 4 kW and 16 kW sensible cooling load. Outdoor conditions are 35 °C, and 50 % RH. Assume that 15 % by weight of the supply air to the room is outdoor air. The recirculated air passed through a cooling equipment and then mixed with the outdoor and conditioned air is supplied to the room at a temperature not lowered than 18 °C. Determine mass and volume of air supplied to the space, tons of refrigeration required of the cooling equipment, average cooling coil surface temperature or APDT.
