Energy. When something is in a solid state its atoms are not moving and their electric charge keeps them close together. As you add energy usually heat they begin to vibrate and thus the attraction lessens. This results in a liquid. Add even more energy and you get a gas.
A state function is a property that depends only on the current state of a system, not on how it got there. In thermodynamics, state functions like internal energy and entropy help describe the state of a system and its changes during processes like heating or cooling.

If you are referring to the BK101 Labpaq kit the question is supposed to be How do the changes in the condition of the potato strips relate to the wilting of plants?
it doesn't
through changes of energy
They aren't; a change of state is a physical change
Physical Changes
When water boils it changes from a liquid state to a gaseous state.
Matter changes state because of pressure and temperature.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
The only changes of state in pure boiling water is from liquid to gas.
