An earthen pitcher loses 1g of water per minute due to evaporation. Thewater equivalent of the pitcher is 0.5kg and the pitcher contains 9.5g of water. Given that Lv of water is 580 cal/g and specific heat of water is 1 cal/g0C, neglecting the radiation effects, show that the time required for water in the pitcher tocool from itsoriginal temperature of 300C to 280C is 34.5 minutes.Give me a detail answer
