Compounds are not generally considered endothermic or exothermic. These terms refer to processes. So, the process of formation, or the process of decomposition, would be an endothermic process or an exothermic process.
A positive enthalpy of formation value tells us that the compound is relatively unstable with respect to its elements, it is an endothermic compound. Similar goes for exothermic compound
A compound is never exothermic. Its reaction with some other substance is endothermic or exothermic like when calcium oxide reacts with water large amount of heat is evolved.
The combustion is exothermic.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
exothermic- because exothermic gives off heat and endothermic is cold
exothermic

Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Silicon is an element - endothermic or exothermic is meaningless.
