Why does water as steam cause severe burns,whereas water as ice has a cooling effect? Explain.
(N/A) Steam contains water particles that possess high kinetic energy due to the latent heat of vaporization. When steam comes in contact with the skin,it releases this extra heat energy,causing severe burns.
Conversely,in the case of ice,the water particles possess lower energy. When ice comes in contact with the skin,it absorbs heat energy from the surroundings (or the body) to undergo a phase change from solid to liquid,thereby producing a cooling effect.
