Why more serious burns are caused by steam at 1000c than water at same temperature?
More serious burns are caused by steam at 100°C than water at the same temperature due to the latent heat of vaporization. When steam condenses on the skin, it releases a significant amount of heat energy, resulting in a more severe burn. Additionally, steam can penetrate the skin more effectively than water, causing deeper tissue damage. Thus, the combination of higher heat transfer and penetration makes steam more dangerous than water at the same temperature.
What is total heat of steam?
The total heat of steam, also known as enthalpy of steam, is the amount of heat required to raise the temperature of water to its boiling point and then convert it into steam without changing its temperature. It is the sum of sensible heat and latent heat of vaporization.
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 is a steam burn an example of latent heat?
A steam burn is an example of latent heat, because beside the heat released by the steam itself, a part of it condenses, turning into water, which in turn releases heat too.
Why 1 kg of steam at 100 degree c cointains more heat against 1 kg of water at same temperature?
The difference is the evaporation heat (or the 'equal' condensation heat)
What is the functions of heat power cycle in a steam power plant?
There is no such thing as a heat power cycle in a steam engine.The power stroke, or strokes, result from pressurised steam being let into the cylinder and moving the piston.
What causes a car to over heat emitting dense steam?
I have no idea what would cause a car to overheat emitting dense steam. When a car overheats, the first thing I check is the thermostat. When a car emits steam, I look for the place where the steam is coming from. I usually think two different problems are happening at the same time.
Steam at 100 C contains the same amount of heat energy per gram as liquid water at 100 C?
For a given mass, steam will have more energy than water. The difference is called the 'heat of vaporization'. One thing to be carefuls about, of course, is that a given mass of steam will occupy much more volume than the same mass of water.
How did James watt create steam?
He applied heat to water. The same way anyone does it.
What are the similarities between steam and mist?
steam and mist are not the same thing
Is the steam engine the same today?
Generally speaking, yes it is the same. It uses the expansion of steam to draw power from the heat energy in the steam. Today's steam engines (turbines) are greatly improved in efficiency over those in use since the 19th century, but they still operate on the same principles.
How are heat and thermal heat alike?
Thermal means heat, so they are the same thing
Which contains more heat energy water at 373K or steam at 373K Why?
Steam at 373K contains more heat energy than water at 373K because it has undergone a phase change from liquid to gas, requiring additional energy (latent heat of vaporization). This extra energy contributes to the higher heat content of steam compared to water at the same temperature.
A kind of engine that uses water steam or heat?
A steam engine uses water, steam, and heat.
Is steam energy the same as geothermal energy?
No, steam energy is produced whenever water is heated, and this can be by burning anything, as well as using heat from under the ground. Geothermal energy is specifically the heat from under the ground, which can be turned into steam to generate electricity.
Why you need coal to generate electricity?
You don't. But coal is an economical fuel. One method of producing electricity on a commercial scale is with steam. Coal provides an inexpensive source of heat to heat water to steam, which is directed through turbines which in turn drive generators. You can do the same thing with falling water (without the steam) if you have a large enough waterfall, or you can use a different heat source like natural gas or atomic energy. Coal is sometimes more economical.
How does nuclear energy involve heat?
In the same way fossil fuel energy involves heat. Making steam to turn turbines.
