A pitcher contains `200kg` of water `0.5 gm` of water comes out on the surface of the pitcher every second through the pores and gets evaporated taking energy form the remaining water. Calculate the approximate time (in min) in which temperature of the water decreases by `5^(@)C`. Neglect backward heat transfer form the atmosphere to th water. (Write the answer to the nearest interger)
Specific heat capacity of water `= 4200 J//Kg^(@)C`
Latent heat of vaporization of water `2.27 xx10^(6)J//Kg`
