2.8.2 Calorimetery Flashcards
1
Q
What are the four types of reaction that can be measured using a calorimeter?
A
- dissolving
- neutralisation
- formation
- combustion
2
Q
What is the equation used to measure heat energy?
A
q=mct
Heat = mass of substance X specific heat capacity X temperature change
3
Q
What is the process of using a calorimeter to find out the enthalpy of combustion for a substance?
A
A known mass of a substance is recorded. The heat energy released in the reaction is absorbed in a known volume of water and the temperature change is measured.

Q
What is the purpose of a calorimeter?
A
The purpose of a calorimeter is to insulate the reaction system from its surroundings
