No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
The process of freezing is an exothermic process. Particles in a liquid have more energy than those in a solid, hence they vibrate / move more. Therefore, to turn a liquid into a solid, energy needs to be taken out of the liquid. This means energy is given off to its surroundings, making it an exothermic process.

Its where heat is taken in in a reaction eg making a cake is an endothermic reaction as heat is taken in to start it ;)
Vaporization is an endothermic process; evaporation is exothermic.
Exothermic- Releases energy. Combustion is a chemical change that releases energy in the form of heat and light. You've taken advantage of an exothermic change if you've ever held your hands near a warm fire. So yes it is an exo thermic change.
The difference is that the endothemic change is when energy is absorbed from the substance and exothermic change is when energy is removed or taken out of the substance.
no
Exothermic Reaction
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
