Thermodynamics is the study of the movement of energy between physical matter, between objects that we can sense (see, feel, smell, hear or taste), and describes for us how energy from physical object effects other physically tangible objects that we can accurately measure. Much of what we measure is the differences of energy, before and after energy exchanges.
We cannot determine the exact energy levels of any thermodynamic system, and at the microscopic level we can only employ thermodynamic statistics to estimate the total energy description of an object.
Energy Exchange: Objects with higher or lower energy levels are required, to either give or receive energy to or from other objects.
An icecube placed on a warmer surface must melt, as the object that is warmer gives it’s energy to the ice, the ice receives energy from the warmer surface transforming it from a solid into a liquid.
This is also an example of a phase or state transition, or from the Quantum perspective, the water is granted more degrees of freedom in which to express itself as its liquid state is more free and energetic than its relatively static solid state.
