Is the melting of candle wax and exothermic or endothermic change?

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 a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
Is melting of candle an exothermic or endothermic reaction?
It is exothermic. When you put your hand close to the burning candle, does the air feel cooler or warmer? If it feels cooler, then it is drawing in heat and is endothermic (endo = in). If it feels warmer, then it is giving off heat and is exothermic (exo = out). (If the system is gaining energy (heat) than it is endothermic, releasing energy is exothermic.)
Is melting butter an endothermic change?
No, it's exothermic. Think of it as ENdothermic as heat ENtering and EXothermic as in EXit. That's an easy way to remember it.
The melting of ice cubes is an exothermic reaction?
No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
Is butter melted in a pan a endothermic or exothermic change?
This is an endothermic process.

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.
Why is burning of candle a exothermic reaction?
Because exothermic change releases energy.
Is melting butter an endothermic change?
No, it's exothermic. Think of it as ENdothermic as heat ENtering and EXothermic as in EXit. That's an easy way to remember it.
Is melting a penny an exothermic change?
Chemical, since it doesn't turn back.
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
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.
The melting of ice cubes is an exothermic reaction?
No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
What change is the opposite of an exothermic change?
endothermic change
