A) How many kilograms of water can be evaporated from a 1 m² surface of water in a lake on a hot, clear summer day, if it is assumed that the limiting factor is the Sun's heat of 1800 Js-¹m-2 for an 8-hour day? Assume that the air and water temperatures remain constant at 40°C.(answer should be 21.6 kg) B) What volume of air is needed to hold this much water vapor at 40°C? (answer should be 423 m³) C) When the Sun sets, the air temperature drops to 20°C. Assuming that the excess water vapor is precipitated as rain, calculate the weight of the rain. Assuming that the excess water vapor is precipitated as rain, calculate the amount of heat released when the water condenses.(weight of water should be 14.1 kg) D) Calculate the vapor pressure of liquid water at 200°C. Assume that the heat of vaporization does not change from its value at 100°C (pressure should be 16.1 bar) ***I provided the answers to each question form back of the book in parenthesis after each question. All i need is work shown how to get to these!***
