Answer 2

When you put ice cubes in a warm drink, the ice melts. This is because the heat from the warm drink transfers to the ice cube, warming up the ice cube and cooling down the drink, right?

Answer 3

right

Answer 4

So when this heat transfer causes there to be MORE heat in the ice cube and LESS heat in warm drink. This means that the energy in the ice cube has INCREASED.

Answer 5

(I think that's what the question is asking)
