I know that we are having trouble with the concept of heat.
Now it appear that internal energy is in trouble. Please
don't define internal energy as the energy a system has by
virtue of its temperature! If you mix some gasoline vapor
and air together you have some internal energy that is not
directly related to the temperature! WBN
