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.
The melting of candle wax is an endothermic change because it absorbs energy from its surroundings to break the intermolecular forces holding the wax molecules together. This energy is needed to overcome the attraction between molecules and change the wax from a solid to a liquid state.
Endothermic because you are melting the sugar cubes, which is when the heat from the inside travels to the outside cooler area.

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.
Is a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
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.
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.
Are Anions are associated with exothermic or endothermic process?
Anions are not associated with either exothermic or endothermic processes on their own. The classification of a process as exothermic or endothermic depends on the overall energy change of the reaction in which the anion is involved.
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?
Melting ice is an endothermic process because it requires heat energy to break the bonds between the water molecules in the solid ice structure to form liquid water. This absorbs energy from the surroundings, making it endothermic.
Is freezing an endothermic change or a exothermic change?
It is an exothermic change
Is a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
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?
Endothermic change absorbs heat from the surroundings, resulting in a decrease in temperature. Exothermic change releases heat to the surroundings, leading to an increase in temperature.
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
