In a particular solid-liquid phase transition the point po, to lies on the coexistence curve. the latent heat of vaporization at this point is lo. a nearby point on the coexistence curve has pressure po+ p and temperature to+ ; the local slope of the coexistence curve in the p-t plane is p/t. assuming v, cp, a, and k to be known in each phase in the vicinity of the states of interest, find the latent heat at the point po + p, to + t.

Inductive or deductive? charles is hard to work with, since he always interrupts others. therefore, i do not want to work with charles in the development committee.

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
