jill activates a reusable hand warmer on a chilly day. as it warms her hands, the liquid inside the warmer crystallizes. describe the process.
a) chemical energy is modified to mechanical energy during the crystallization.
b) the energy in the liquid is reformed in an endothermic crystallization reaction.
c) the energy of the supersaturated liquid is converted to heat as the compound crystallizes.
d) the kinetic energy in the liquid is transferred to the crystals is an

The answer is letter C, The energy of the supersaturated liquid is converted to heat as the compound crystallizes.

Explanation:

"Hand warmers" are very essential when the cold season comes. It provides warmth to the hands, especially when going outdoors. There are different kinds of hand warmers, such as the "reusable hand warmer." In contrast to air-activated hand warmers, the reusable hand warmers contain sodium acetate (not iron).

Sodium acetate is a "supersaturated liquid." This means that is has more substances dissolved in it. So, when this crystallizes, heat is released. Remember that crystallization is considered an "exothermic process." This means that the process releases energy (in this case, through "heat").

Thus, this explains the answer, letter C.
