Webbthermometer (thər-mŏm′ĭ-tər) n. An instrument for measuring temperature, especially one having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases. The American Heritage® Medical Dictionary Copyright © 2007, 2004 by Houghton Mifflin Company. Webb8 apr. 2024 · Het kalibreren van een thermometer geeft nauwkeurige temperatuurmetingen. Verschil tussen temperatuur en warmte. Temperatuur (T) en warmte (Q) zijn nauw verwant, maar niet hetzelfde. Warmte is de overdracht van kinetische energie van het ene lichaam naar het andere, wat op zijn beurt hun temperatuur verandert.
