Okay guys,
My chemistry teacher sucks.
REALLY sucks.
The other day he put the words 'epthalmy' and 'calorimetry' on the board, and being the trusting person I am, I expected him to explain. But no. We were just told to write them down. And flipping google them.
But I can't seem to grasp exactly what they are, and why, how, when they're used?
And now I have an assignment on it.
HELLLLLLPPPPPP

Enthalpy - the amount of energy released (or absorbed)
Calorimetry - the device you boil with your chemical to find the enthalpy.

Calorimetry: Calorimetry is the science of measuring the heat of chemical reactions or physical change (from Wiki)

E.g. determining the heat of combustion of ethanol by heating water.

Doesn't your text book have good explanations/ definitions?
