Sam leaves his Popsicle on the counter in the kitchen. What would happen if he returned after

two hours? How is the heat being transferred in this example?

In the timelapse between leaving the popsicle and returning to it in the duration of two hours, Sam will discover that the popsicle has lost it's cold exterior to nonetheless the surroundings.
