About the Law of Conservation of Energy…?

Energy can neither be created nor destroyed.

However, it can be converted from one form into another in an exact equivalence.

There are conditions though.

1. Some forms of energy are in a higher state of availability. e.g., Mechanical, and electrical.

Heat is one of the lowest forms of energy in terms of availability.

2. The classic Einstenian E=mc^2 seems to go against this. But this is applicable only to nuclear reactions in which there can be differences in mass. This ‘mass defect’ appears as energy.

e.g., fusion of hydrogen atoms to form helium leads to a small reduction in mass. This produces enormous energy in the sun.

There is lots more. But this is not the forum for a detailed discussion.

>The first part (Energy can neither be…by ordinary means) means that there is the same amount of energy every where. It cannot be created by ordinary means. That indicates that it can be created, but not ordinnarily. In nuclear powerplants energy is created, but of course it’s not created ordinarily. The sum of all the energies in the system is constant.

I forgot the second part. Sorry.
