The answer is endothermic.

The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat). If the reactants give off heat of their own (self sustaining), then it is an exothermic reaction.

There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.

Is melting of candle an exothermic or endothermic reaction?

The melting of a candle is an endothermic process because heat is required to break the intermolecular forces holding the solid wax together and convert it into a liquid. Energy is absorbed during this phase change.


Why is burning of candle a exothermic reaction?

Because exothermic change releases energy.


Is melting a penny an exothermic change?

Chemical, since it doesn't turn back.


Is melting ice endothermic or exothermic change?

Ice cream melting (or pretty much anything melting) is an endothermic process in that it requires the absorption of heat energy in order to occur. An example of an exothermic process is the burning of paper which gives off heat energy.


Is a candle a endothermic or exothermic change?

exothermic- because exothermic gives off heat and endothermic is cold


Is freezing an endothermic change or a exothermic change?

It is an exothermic change


Compare endothermic and exothermic?

An endothermic change requires heat, and an exothermic change releases heat.


Is melting butter an endothermic change?

Melting butter is an endothermic change because it requires the input of energy to break the intermolecular forces holding the solid butter together. This energy is absorbed from the surroundings, resulting in a decrease in temperature around the butter as it melts.


Which of these processes have the same magnitude of energy change but are opposite in sign?

Endothermic and exothermic reactions have the same magnitude of energy change but are opposite in sign. In an endothermic reaction, energy is absorbed from the surroundings, while in an exothermic reaction, energy is released to the surroundings.


What is the difference of the endothermic and exothermic change?

An endothermic change requires heat, and an exothermic change releases heat.


Is butter melted in a pan a endothermic or exothermic change?

Melting butter in a pan is an endothermic process. It requires energy input to break the bonds of the solid butter and convert it into a liquid state.


What change is the opposite of an exothermic change?

endothermic change
