6. The following measurements or estimates were made of the radiative fluxes over a short grass surface during a clear sunny day: Incoming shortwave radiation = 675 W/m² Incoming longwave radiation = 390 W/m² Ground surface temperature= 35 °C Albedo of the surface = 0.20 Emissivity of the surface = 0.92 a. From the radiation balance equation, calculate the net radiation at the surface. b. What would be the net radiation after the surface is thoroughly watered so that its albedo drops to 0.10 and its effective surface temperature reduces to 25 °C c. Qualitatively discuss the effect of watering on other energy fluxes to or from the surface.

Why we use a number of antimony-bismuth couple in a thermopile?
Derive a formula, similar to equation (attached), for the shift in the freezing temperature of a dilute solution. Assume that the solid phase is pure solvent, no solute. You should find that the shift is negative: The freezing temperature of a solution is less than that of the pure solvent. Explain in general terms why the shift should be negative. Use the result of the above to calculate the freezing temperature of seawater.

A U – tube with some mercury at the bottom is set up vertically and twelve centimeter of water is added into one arm of the tube. Methylated spirits is then added carefully into the other arm of the U – tube until the mercury levels are the same in both arms. It is observed that the level methylated spirit is higher. What is the density of methylated spirit if the methylated spirit column is fifteen centimeter high?Required to answer. Single choice.
