Is energy absorbed during freezing

Answer 1

depends on your point of view, but... it's not really absorbed in the strictest sence. by "freezing", i'm assuming you're intent is to say you are taking some substance, say water at room temperature, & then freezing it (lower it's temperature to or below the point at which the water becomes frozen).

what happens to the energy is, it is transferred out of the water, to somewhere else. if using a common refrigerator/freezer, the heat energy from the water is transferred to the air outside the frig, by use of gas compressor in the frig. a simpler way to look at it (but essentially the same thing... just a "one shot" in a sense) would be by using some compressed gas like liquid nitrogen & spraying the water with the liquid nitrogen. since liquid nitrogen boils at roughly -320 f (195.79 C), you would be transferring much of the heat energy stored in the water, into the liquid nitrogen, thus freezing it.
