Answer:
The water molecules strike the atoms of the spoon and transfer some of their energy to these atoms. ... So when energy is transferred from the water to the spoon, the spoon gets warmer and the water gets cooler.
Heat can move from one point to another in three basic ways: by conduction, by radiation, or by convection. ... This transfer of heat occurs from the hot coffee and hot mug to the surrounding air. The fact that the coffee lowers its temperature is a sign that the average kinetic energy of its particles is decreasing.
The rapidly moving molecules in the boiling water bump the molecules in the metal spoon. This bumping transfers kinetic energy to the molecules that make up the spoon, causing them to vibrate faster. ... The reason the hot spoon burns your hand is because heat is transferred to your skin by conduction.
