39
_______ occurs when a substance absorbs heat energy. It is the process of going from solid to liquid. It has a ___________ reaction. For its particle behavior, it ________ in place and moves more freely.
40
________ occurs when heat energy is lost. It is the process of going from liquid to solid. It has a ___________ reaction. For its particle behavior, it moves freely and is locked into a _____ position.
41
___________ occurs at the surface without boiling. It is the process of going from liquid to gas. It has a ___________ reaction. For its particle behavior, it spreads out _______ and moves fast.
42
____________ occurs when heat energy is released. It is the process of going from gas to liquid. It has a ___________ reaction. For its particle behavior, it _____ down and comes closer together.
43
___________ requires energy input. It is the process of going from solid to gas. It has a ___________ reaction. For its particle behavior, it breaks free directly into a ___ state
44
__________ releases energy. It is the process of going from gas to solid. It has a ___________ reaction. For its particle behavior, the gas particles slow down so much that they form a _____.
