Answer:
Liquid
Step-by-step explanation:
Liquid can change into all states of matter. For example, if you boil it, it becomes a gas, if you freeze it, it becomes a solid, and if you split the atoms, it can turn into a plasma. In conclusion, any state of matter has potential energy that needs a little push to activate it, hence the one of newtons laws of physics; every action has an equal and opposite reaction.
