Heat is always a transfer of energy from objects at a higher temperature to a lower temperature. There are 3 different ways this transfer of energy can happen. Alison Stirling . 21. st.

In the real world, because of friction and other imperfections and the natural composition of the system, the steady state of the output response seldom agrees exactly with the reference. .
