When water vapor loses energy what phase change occurs?
When water vapor loses energy it "turns" into a liquid
Does water lose absorb heat energy when it condenses?
The change of state of water from liquid to vapor, or the reverse from vapor to liquid, involves a fixed amount of thermal energy per unit mass, this is called the specific latent heat. To evaporate liquid water to vapor, heat must be supplied, whilst in condensing vapor to liquid, heat is released. Similar rules apply to water when it changes from liquid to ice, or ice to liquid. You can look up the amount of the latent heat in physical tables.
Does condensation lose or gain energy?
Condensation gives off energy. Matter is moving from the higher energy vapor state to a lower energy liquid state. This is an exothermic process.
How are water droplets form when water is boiling?
Water has 3 states, solid(ice), liquid(water, and gas(Water vapor). When water is boiled, it gathers heat energy. It then becomes a gas , breaking away from other water particles. it gathers together on a colder surface and loses some of that energy, reverting it back to water.
What happens to water vapor when energy is taken away?
If enough energy is taken away from water vapour, it will condense to form water (in liquid form). This is because a gaseous state requires more energy than a liquid state (and a liquid state requires more energy than a solid state).
When does saturated vapor condition exists in HVAC?
All of the liquid has boiled to a vspor
When water vapor loses energy what phase change occurs?
When water vapor loses energy it "turns" into a liquid
What is water changing from gases to liquid?
Water changes from a liquid to gas when boiled. (boiling point = 110 Celsius)
Occurs when water vapor changes to liquid water?
Its a change in energy primarily. Water vapor loses energy and then becomes liquid. The energy it loses generally is heat. For example, Put water vapor in a sealed container in a freezer, it will change from vapor to liquid, then liquid to solid as it loses energy in the form of heat
What is meant by saturated liquid vapor?
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.
When water vapor loses energy may into a liquid?
Condense
When water vapor loses energy. it may into liquid?
Condense
What caused the water to change from liquid water to water vapor?
Either evaporation or the water was boiled. But, in general explanation, the molecule of water need certain energy to break its inter molecular force to cause it being vaporized. So if the quantity energy needed is fulfilled, the state is changing from liquid to gas.
The process of changing from liquid to vapor?
causes heat energy to flow from the liquid and cool the surroundings.
What does liquid become when it absorbs enough energy?
It becomes a gas/vapor.
When a liquid absorbs enough energy it becomes a what?
It becomes a gas/vapor.
When a water vapor loses energy it may turn into liquid?
Condense
