Provide a very simple example in which you personally have experienced heat loss (feeling colder) during evaporation of water from your body.
Next, find from the text or the Internet the numerical amount of heat required to evaporate one gram of water at normal surface temperatures on the earth.
Explain how this value compares and contrasts with the amount of heat (one calorie) needed to change the temperature of one gram of water by one degree C.
Does the difference in magnitude surprise you? Explain why or why not.
Discuss the implications of your findings on these two values. Consider the development of clouds and think about its impact on the formation and maintenance of thunderstorms. Use the concepts of stability and instability.
