Heat transfer, chemical engineering ?

6. A woman informs her engineer husband that \"hot water will freeze than cold faster water.\" He calls this statement nonsense but he does so in a polite She answers by saying that she has actually timed the freezing process for ice trays in the home refrigerator and found that hot water does indeed freeze faster. As a friend, you are asked to settle the argument and preserve family harmony. Is there any logical explanation for the woman\'s observation

Solution

yes it is, as the initially warmer water cools to the iitial temp. of the initially cooler water, it maylose significant amount of water to evaporation. the reduced mass will make it easier for the watr to cool and freeze. then the initially warmer water can freeze beforethe initially cooler water, but will make less ice.
