lämpötilahysteresi
Lämpötilahysteresis, or temperature hysteresis, refers to the phenomenon where the property of a material or system depends not only on the current temperature but also on its thermal history. This means that the value of a property at a given temperature can be different depending on whether the temperature was reached by heating or cooling.
This effect is commonly observed in phase transitions, such as melting and solidification, or in magnetic materials.
The underlying cause of temperature hysteresis is often the presence of metastable states. These are states
