Steam itself is not endothermic or exothermic - only chemical reactions can be labelled as exothermic or endothermic
the reaction whithin the steam can only be exothermic or endothermic

∙ 13y agoSteam condensing is an exothermic process since the water vapor (steam) must lose or give off heat in order to return to the liquid state.
Wiki User
∙ 14y agoWhile cooling the water, energy is leaving as heat. Any time energy is released, it is an exothermic process.

Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
What is the source of energy that fuels a thunderstorm?
heat released from condensing water vapor
What is the process called that changes water vapor to water?
the answer is condensing edit: condensation
Is water vapor condensing to form rain a physical or chemical change?
Condensation is a purely physical process (a change of phase). Water evaporating or condensing does not change its molecular composition (H2O).
Is rain turning into snow exothermic or endothermic?
Precipitation has to be an exothermic process. We know this because the overall entropy change having to be positive (second law of thermodynamics) - and because the entropy change of the system is negative (two liquids forming one solid and one liquid) the entropy change of the surroundings must be positive (and also large enough to make up for the decrease in entropy of the system) for the overall entropy to be positive and the reaction to be spontaneous. Positive entropy of the surroundings equates to a negative value for delta H (and therefore an exothermic process).
Is gas to liquid endothermic or exothermic?
The liquid to gas phase transformation (evaporation) is an endothermic process. It requires heat to be accomplished. The gas to liquid phase transformation (condensation) is an exothermic process. The vapor releases heat while condensing into a liquid.
Is liquid mercury changing to a vapor exothermic?
No, is is endothermic- requires heat
Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
Is water evaporating an exothermic process?
The evaporation of water is endothermic. In order for the hydrogen bonds to be broken in water (which is required for water to evaporate), an input of energy is needed. Conversely, the condensation of water vapor is exothermic.
What occurs at the cloud base where water vapor begins condensing?
At the cloud base when water vapor begins condensing it begins to release it. This releasing is called rain.
When you beathe onto a cold window and water droplets appear it is an example of?
Condensation. The water vapor in your breath (a gas) is chilling, and condensing into liquid water on the glass.
What are formed from cooled water vapor condensing?
fog
What are the water droplets outside of a glass is?
The water droplets are the result of the humidity in the air colling down and condensing on the outside of the glass. When water evaporates it turns into water vapor or steam we call the amount of water vapor in the air humidity. condensation is the reverse of evaporation and is also responsible for rain.
How are storms clouds and water vapor all connected?
All clouds are condensing water vapor.
What is the process of purifying a liquid by boiling it and condensing its vapor?
DISTILLATION
Is condensation af water vapor into rain exothermic?
no...
What is an example of a gas-liquid?
The condensing of water vapor in to water dropplets
