Cards (5)

what is the law of conservation of energy?
the overall amount of energy does not change as energy is conserved in reactions
T or F
energy cannot be created or destroyed, so it can not be transferred
F - it can be transferred
what is an exothermic reaction?
a reaction that releases heat energy - increasing the temperature
what are examples of exothermic reactions?
neutralisation
combustion
what are endothermic reactions?
a reaction that takes heat energy in - this means that the temperature decreases
