Document Summary

Equations 0o c = 273. 16 k cice = 2090 j/kg k. Water: (1) suppose you could harness the electromagnetic output power of a t = 2000 k object with surface area. Na = 6. 022 x 1023 s = 5. 67 x 10-8 w/m2 k4. Lfusion = 3. 33 x 105 j/kg lvap = 2. 26 x 106 j/kg. R = 8. 314 j/mol k cliquid = 4186 j/kg k. A = 1 m2 and emissivity e = 1. Heat the ice to 0oc: q1 = cice m (0oc tice) Heat the water to 90oc: q3 = cliquid m (tw 0oc) energy required: q = q1+q2+q3 = 752 kj. Power emitted by object: p = saet4 = 907 kj/s. Time required: t = q/p = 0. 83 s (2) for the cycle shown in the figure, find w, q and deint in joules for each process and for the entire cycle. The working substance is n = 0. 250 moles of an ideal gas.
