Humans are unable to convert radiant energy from the sun into stored energy that can be usedto do work. Plants, however, obtain their energy from photosynthesis – sunlight is used toconvert carbon dioxide and water into sugars (stored as an energy source) and oxygen.Consider a leaf with a surface area of 2.5 cm2. On a sunny day it might receive sunlight withan average power per unit area of 350 W/m2. Of this incident light, only about 40% is usefulfor photosynthesis. (a) If the process was perfectly efficient (i.e. all the useful radiation was converted tostored internal energy), calculate the increase in internal energy of the leaf in aperiod of one hour. (b) In practice, the overall efficiency of the process (percentage of energy storedrelative to the total incident energy reaching the surface of the leaf) is only about6%.

The planet Venus is different from the earth in several respects. First, it is only 70% as far from the sun. Second, its thick clouds reflect 77% of all incident sunlight. Finally, its atmosphere is much more opaque to infrared light. Estimate the surface temperature again, taking the reflectivity of the clouds into account.
