olomuodonmuutoslämpö
Olomuodonmuutoslämpö, also known as latent heat, is the energy absorbed or released by a substance during a phase transition, such as melting, freezing, vaporization, or condensation, at a constant temperature. This heat is not associated with a change in temperature but rather with a change in the physical state of the substance. For example, when ice melts into water, it absorbs a specific amount of energy, the heat of fusion, without its temperature increasing until all the ice has melted. Similarly, when water boils and turns into steam, it absorbs the heat of vaporization.
The amount of energy required for a phase change is characteristic of the substance and the specific
