Problem 11CQ In very humid climates where there are numerous bodies of water, such as in Florida, it is unusual for temperatures to rise above about 35C(95F) . In deserts, however, temperatures can rise far above this. Explain how the evaporation of water helps limit high temperatures in humid clim
