The process is called facilitated transport when molecules must join with another molecule, such as proteins, to get through a membrane.
The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
With the graph attached below you can determine when was the moment that
<span>Sally tripped and fell.
You can also see that they run for 4 minutes before starting to rest. Then, after resting 10 minutes (starting at the 9 min mark and ending at 14) they started running a bit, that's why the line is not at zero anymore. After moving a bit, between 15 and 16 min mark, they stop distancing for one minute. So the answer is: Sally fell at the 15 min mark.

When plants are allowed to self-fertilize generation after generation, the exact same physical traits appears without any change. Such plants are called pure line or true-breeding. For example, tall plants always produce tall plants and true-breeding dwarf plants always produce dwarf plants on selfing.
