This logical extension is, of course, trivial!

It describes how water circulates, absorbs heat, and is cooled in the radiator. The concept of specific heat is introduced through the formula \(q = c_p \times m \times \Delta T\), allowing for calculations of heat absorption, mass, and temperature changes. Examples illustrate how to compute specific heat and predict final temperatures during heating or cooling.
