What's the difference between calorimeter and calorimetric?
Calorimeter
Definition:
(n.) An apparatus for measuring the amount of heat contained in bodies or developed by some mechanical or chemical process, as friction, chemical combination, combustion, etc.
(n.) An apparatus for measuring the proportion of unevaporated water contained in steam.

Calorimetric
Definition:
(a.) Of or pertaining to the process of using the calorimeter.
Example Sentences:
