What is the law of the conservation of energy
the overall amount of energy does not change as energy is conserved in reactions
What is an exothermic reaction
Releases heat, products cool, surrounding temp increases
Endothermic reactions
Atakes heat energy in, temperature decreases, products heat up
examples of heat changes in reactions
Neutralisation reactions, These always give energy out
Displacement reaction, These can either take energy in or give it out
Combustion reactions, These always give energy out
What is calorimetry
the study of heat changes in a reaction. It helps measure how much heat is absorbed or released during chemical reactions, changes of state, or when substances are heated or cooled.
