An experiment is done where 5 grams of ice is kept in 2 different boxes for 15 minutes. After the 15 minutes, the ice cubes are brought out and weighed.
Box 1 is made of conducting materials. Box 2 is made of insulating materials. Which piece of ice would you expect to weigh more? Why?
The ice from box 2. Insulators slow down heat transfer so less heat could get to the ice to melt it.
