explain what ways to the molecular motion and energy of 1 kg of water at 273 Kelvin when it is changed ice at same temperature how is the latent heat of fusion related to the energy exchange that take place during this change of state

hii ,
here is your answer,
---------------
●When water is converted to ice, the molecular motion decreases as heat is released to the surroundings.
●Energy of 1kg water = latent heat x Mass
= -80cal/g x 1000 g
= -80,000 cal
(-) sign indicates that thermal energy is decreased.
●Therfore, when 1 kg water is converted to ice at same temperature, 80,000 cal enrgy is lost.
●Latent heat of fusion is the amount of heat(energy) which is taken from the surrounding or added to the system in order to change it from solid to liquid at constant temperature.
hope it helps u! !!!
