Water has a boiling point of 100 degrees Celsius. When water reaches this point it becomes a gas (steam). Therefore you can say that the average temperature of steam is around 100 degrees Celsius.
Answer:
Steam is not the white plume from the spout of a kettle, but the hot uncondensed water vapour before this condensation takes place. It has a temperature equal to the liquid it comes from. This is not limited to 100oC except in systems that are open to the standard atmospheric pressure of 760 mm Hg.
In high pressure industrial borders steam temperatures can be several hundred degrees centigrade at several atmospheres pressure. Conversely at extreme elevations water boils far below 100oC and the steam is correspondingly cooler.
At normal atmospheric pressure at sea level, steam is at least 100 degrees Celsius or 212 degrees Fahrenheit. There's not really an upper limit. The steam going into the turbines of a power plant, for example, might be 400 degrees Fahrenheit or more.
More than 100 degrees Celsius, or 212 degrees Fahrenheit.
212....the temp when water turns to vapor
212 Fahrenheit
what is the temp of 700lb/hour steam
dissipates
Latent heat of condensation.
When you heat the can with water, the water inside turns into steam. When the can is then placed in the cool water, the steam condenses back into water, creating a pressure difference between the inside and outside of the can. This pressure difference causes the can to collapse.
water vapor condenses to a liquid
Due point of water
Actually when steam condenses it is loosing heat. As steam rises it cools and falls back down with gravity. I.E. a steam boiler heat system Boils water to till it turns into a gaseous mixture of water droplets and rises to a radiator to heat. As the radiator absorbs the heat from the steam It condenses and returns to the boiler through the same riser pipe to the boiler.
dissipates
It really depends on the temperature of the steam and temperature of the cold surface. 250 degree steam hitting a 50 or 60 degree surface will just turn back into water and droplets can be seen almost immediately. 1000+ degree steam hitting a frozen surface may cause a loud bang and eventually turn back into water.
It condenses and turns into vapour which is known as "steam".
steam
with the pressure we can increse it to 270 deg centigrade
Latent heat of condensation.
When steam condenses to form water, it releases energy in the form of heat to the surroundings. This energy is needed to break the intermolecular forces that hold the water molecules together as steam.
by the way the steam condenses back to water
its in a cycle. water is heated to produce steam which spins the turbine. and when steam condenses it forms water which can be evaporated again
Yes, it is. When steam condenses into water, the water molecules lose energy and this energy is transferred to the surroundings. Loosing energy is exothermic.
Steam rises off a lake in winter because the water in the lake is warmer than the surrounding air temperature. When the cold air comes into contact with the warm water, it causes the water to evaporate and rise as steam or water vapor.
