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.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
It represents the change in enthalpy for the reaction.

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.
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.
Endothermic changes are processes where energy is absorbed by the system from its surroundings. This results in a decrease in temperature in the surroundings during the process. Examples include melting ice and evaporating water.
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
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.
