EXOTHERMIC: any combustion
ENDOTHERMIC: evaporation of liquids
Heat is released during an exothermic reaction.
The combustion is exothermic.
Rusting is an eXothermic reaction, not an eNDothermic.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Physical endothermic change because it uses energy (taking up heat)
Silicon is an element - endothermic or exothermic is meaningless.
Exothermic reaction.
exothermic- because exothermic gives off heat and endothermic is cold
