Calorimetry
Device used for calorimetry
What is a calorimeter
The heat of any reaction for a specific reaction is equal to the sum of the heat of the reaction for any set of reactions which in sum are equivalent to the overall reaction.
What is Hess's Law?
This law is the law of thermodynamics that relates to entropy.
What is 2nd?
The units T is measured in
What is Kelvin
Used to calculate food calories
What is bomb calorimetry?
This object is generally used for calorimetry in the classroom.
What is a Styrofoam cup?
The standard unit for measuring heat
What is a Joule?
A word for thermodynamic favorability
The Grand Daddy equation
Adding shifts away
What is Le Chatlier's rule?
