It specifically explains Bohr's hydrogen atom model, which accurately predicts the Balmer series of spectral lines but falls short for multi-electron atoms.

It describes how water circulates, absorbs heat, and is cooled in the radiator. The concept of specific heat is introduced through the formula q=cp×m×ΔT, 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.
