Answer:
When water is added to quicklime rise in temperature is observed. This is an example of an exothermic reaction.
Exothermic reaction
An exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus, in an exothermic reaction, energy is transferred into the surroundings. In an exothermic reaction, the change in enthalpy (ΔH) will be negative.
What happens when quicklime is added to water?
When quicklime is added to water, it forms slaked lime along with the evolution of heat. There will be a rise in the temperature of the bucket. Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.
CaO + H2O → Ca(OH)2
