What exactly is energy....without using symbols and metaphors?

[Chatha]

Maybe its my inability to express my question, but so far my question hasn't been answered.

Say you heat up a container full of a gas. Energy will be transferred from the heat source to the gas, and thus the kinetic energy increases. But what exactly is happening. What is being transfered. Try to explain it to me without using the word 'energy.'

My dear friend I have given you the answer you seek-change. Everything changes but for nothing can change without energy. Change is what you simply observe when you boil water. Change can be observed in many different viewpoints and can produce a million variables in form. Change my friend, change. You must remember we live in a universe in motion, not one of a frozen frame. Otherwise you have to ask yourself where did the first motion which caused all other motions come from? I leave that to you to answer.

Energy is often described/explained/thought of in terms of symbols and metaphors, but what exactly is it? Molecules that are very hot have lots of kinetic energy, but what makes them vibrate/move in such a way? What exactly is the energy doing. I'm having trouble asking my question, so hopefully someone else will understand what I'm trying to ask --and will be able to provide an answer.

Energy is maximally decompressed mass that can be represented in multiple forms (heat, light, sound, charge, etc), converted to mass, and produce work. What's mass? Nobody knows for sure at the moment.
