Feels cold to the touch: Since energy is absorbed from the surroundings, an endothermic process often feels cold to the touch. 4. Examples: a. Melting of ice: The ice absorbs heat from the surroundings to change from solid to liquid state. b. Evaporation of water: In this process, water molecules gain energy from the surroundings to vaporize. c.
