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.
