... It follows from this that if you do a certain amount of work to raise an object to a new height then the work you do to get it there must be equal to the amount of energy that it has gained - provided that the energy transfer is 100% efficient. So, if you raise an object to a new height it gains ene ...

... This is a somewhat more subtle statement than might appear at first sight. We have defined the heat capacity in terms of the amount of heat needed to raise the temperature of a substance by one degree, but we have not stated what heat is. The most rigorous approach is to define first of all the inte ...

What is energy?
... Assuming there is no input of energy (closed system), when energy is converted from one form to another, the amount of useful energy in the system decreases. Entropy is the tendency toward an increase in randomness and disorder in a closed system. ...
