Boiling water seems simple, but it hides one of the most important ideas in thermodynamics. Once water reaches its boiling point, adding more heat does not keep raising its temperature the way many people expect. Instead, that energy is used to change liquid water into water vapor, which is why boiling water stays around 100 degrees Celsius under normal pressure.
This short video explores why temperature is not just about how much heat is being added, but what that energy is doing. Water can absorb energy, lose energy, change state, and transfer heat to its surroundings, all while revealing the difference between temperature and thermal energy. For anyone curious about boiling, phase changes, heat transfer, or why everyday science does not always behave the way it seems, this topic is a surprisingly clear way to understand how energy moves through matter.
