Is burning gasoline an exothermic process or an endothermic process?

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.
