  • paisumistegur, mis kirjeldab, kuidas objekti kontuur muutub temperatuuri muutumisega
  • coefficient of thermal expansion describes how the size of an object changes with a change in temperature
  • linear thermal expansion coefficient of a material at 20 0C
soojuspaisumistegur preferred
Usage examples
  • Soojuspaisumistegur iseloomustab objekti kalduvust muuta oma kuju, ruumala ja mahtu vastuseks temperatuuri muutusele.
ruumpaisumistegur
Usage examples
  • Ruumpaisumistegur näitab seda, et materjali ruumala muutub mõne fikseeritud murdosa võrra, nii nt võib terasplokk ruumalaga 1 kuupmeeter laieneda 1,002 kuupmeetrini, kui temperatuuri tõstetakse 50 K võrra.

Usage examples
  • Coefficient of thermal expansion that the volume of a material changes by some fixed fractional amount. For example, a steel block with a volume of 1 cubic meter might expand to 1,002 cubic meters when the temperature is raised by 50 K.
