Molecules in the cake are moving faster than molecules in the skin.

Explanation:

When a cake is baked, the energy is absorbed. This is known as an endothermic reaction. When things are hot, it means that the molecules are in motion. When the cake is taken out from the oven, the molecules are continuously moving and absorbing energy. When the student touches the cake, the heat is flown into the student's body. This happens because of the difference in the temperature between the two.
