condensation of rain from water vapor - Answer melting ice cubes Melting ice cubes are an example of an endothermic process, because heat energy is taken from the surroundings when ice cubes melt. Burning sugar and a candle burning are both chemical reactions which give off heat energy, so they are both exothermic. When water vapor condenses, more energetic gas molecules become less energetic liquid molecules; the heat energy from the more energetic molecules in the gas phase is given off ...
