Q.
I would like to know how the oxygen calorimeter works, if you don't mind.
Is it required that the sample be dried first?

If a wet sample was placed in the calorimeter with equivalent one gram
dry weight would the results be the same as a one gram dry sample? That
is, does the water in the sample lower the calorimeter value when measured?
