What is an exothermic reaction?
One which gives out energy to surrondings, usually in the form of heat and usually shown by a rise in temperature of the surrondings.
3 of 5
What is an endothermic reaction?
One which takes in energy from the surrondings, usually in the form of heat and usually shown by a fall in temperature of the surrondings.
