It is endothermic. Endothermic is to gain heat and Exothermic is to lose heat.
Endothermic. The water must gain energy in order to evaporate.
a liquid requires heat to evaporate si it is endothermic process.
Endothermic
endothermic
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
Yes, bats are endotherms
Vaporization is Endothermic
Endothermic because it is gaining/absorbing heat.
Yes, vaporization is an endothermic reaction while freezing is an exothermic reaction. Think of a pot of water set of the stove. What are you doing to it? You're putting in heat in order to break the hydrogen bonds. The heat/energy is being expendedor absorbed to make the water boil. In the case of freezing (say water), the hydrogen bonds are realigning while producing heat.
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
The combustion is exothermic.
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.
Silicon is an element - endothermic or exothermic is meaningless.
Exothermic reaction.
exothermic- because exothermic gives off heat and endothermic is cold
Vaporization is an endothermic change.
