transition temperature
"Transition temperature" is a key concept in physics, chemistry, and materials science, indicating the temperature at which a material undergoes a significant change in its physical properties.
Definition
B2General
(technical)The temperature at which a material undergoes a significant change in its physical properties.
Example
- The transition temperature of water is 0°C, where it changes from solid to liquid.
B2Phase Change
(technical, academic)The temperature at which a substance changes from one state of matter to another, such as from solid to liquid or liquid to gas.
Example
- Ice melts into water at its transition temperature of 0°C.
C1Materials Science
(technical, academic)The temperature at which a material changes its crystal structure or magnetic properties.
Example
- The transition temperature of iron changes its magnetic properties.
C1Superconductivity
(technical, academic)The temperature below which a material becomes superconducting, exhibiting zero electrical resistance.
Example
- Yttrium barium copper oxide becomes superconducting below its transition temperature of 92 K.
C1Polymers
(technical, academic)The temperature at which a polymer changes from a brittle, glassy state to a flexible, rubbery state.
Example
- The transition temperature of this polymer determines its usability in different environments.
