How much energy is released when a substance is cooled to its original temperature?
It depends on it's original temperature and how much it was heated.
Which has higher temperature steam or water boling in kettle?
Steam. The reason for this is water boils at the temperature of 212 degrees F. Steam can be heated to much higher temperatures than that. Some engines that are water cooled has steam at temperatures of over 700 degrees. Water basically becomes a plasma at this temperature.
How many joules of energy are necessary to heat the steam from 100.0 degree c to 114.0 degree c?
That completely depends on how much steam there is. (mass)
Why more serious burns are caused by steam than water at same temperature?
The heat content of 1 gram of steam of 100oC is much higher than that of 1 gram of 100oC, the extra comes from condensation heat (energy).
How much bacteria gets killed from steam?
The amount of bacteria killed by steam depends on various factors such as temperature, exposure time, and bacterial species. Steam can be an effective method for killing bacteria as the heat can denature and destroy proteins essential for bacterial survival. However, some heat-resistant bacteria may require higher temperatures or longer exposure times to be effectively killed by steam.
How much heat is released when 1000g of steam at 100 degrees Celsius condenses?
540 kcal
Why is heat trasnfer coefficient of saturated steam is higher than superheated steam?
when steam is at its saturation point for a given pressure, any heat removed will cause liquid water to form. So when saturated steam is used to heat something else, the heated object/substance receives the condensation heat of the steam. The latent heat of condensation/evaporation is 970 But/lb @ 0 psig. On the other, superheated steam only gives up about 10 BTU/lb if it is cooled 20 degrees F. That means that much more steam would be used to transfer the equivalent amount of heat. The liquid water interface also improves the heat transfer.
Fifty grams of water cooled from 50 degrees to 10 degrees if the specific heat of wayer is 4.2 hoe much was released?
If fifty grams of water cooled from 50 degrees to 10 degrees, and the specific heat of water is 4.2, 135 kJ of heat was released.
How much heat is released when 12.4 g of steam at 100 degrees celsius condenses to water at 100 degrees celsius?
The latent heat of condensation of steam is 2260 Joules per gram (539.3 cals/g). So the amount of heat released by 12.4 g = 12.4*2260 Joules = 28,024 Joules or 6687 cals.
How much heat in kilojoules is released when 25.0 g of water is cooled from 85.0ºC to 40.0ºC The specific heat of water is 4.184 J(gC).?
q = mC∆T where q=heat; m=mass of water; C=sp.heat; ∆T=change in temp.q = (25.0g)(4.184 J/g/deg)(45 deg) q = 4707 J of heat released
How much steam is made on a Navy ship?
It depends on the ship in question. Steam is often used for things other than just propulsion. It is sometime used to heat a ship and to heat hot water. Nuclear and steam vessels run their power on steam.
How much heat gives 1 kg of steam?
756.78 degrees Celsius
Why the water cooled condensers have to be used in the water steam cycle of power plant?
Some of the heat is used to produce electricity, the rest is waste and put into the environment. Much of the energy of the heat is lost as the steam passes through the turbines, with the heat being converted to mechanical energy, and then to electrical. This accounts for about 35% to 40% of the energy of the heat, cooling it by the removal of that heat. It would be possible for residual heat to be tapped for conversion into electricity, also, but this is not done in most nuclear reactors. Converting it to electricity would get another 10% or so of the heat of the remaining steam, cooling the steam further. The remainder of the heat is waste. It is dumped into the environment, primarily into the air, by using heat exchangers and cooling towers. In this system, the steam is used to heat water, condensing in the process. The water is then used to heat air in the cooling tower. Another way to get rid of waste heat is to use heat exchangers to heat a nearby body of water, such as a lake, the ocean, or a river. This is usually done only in the summer, when the atmosphere is warm and the cooling towers are not efficient enough to do their work.
When 30 grams of water is converted into steam how much heat is absorbed?
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
What is meant by wet and dry steam?
Dry steam is superheated , meaning more heat has been added resulting in no liquid phase present and the heat of vaporazation has been surpassed adding to the total enthahpy of the vapor. Wet steam is much like the steam rising from a pot of boiling water.
