How is stored chemical energy converted into thermal energy when coal is burned to make steam?
It's converted by the coal being burned.
What happens to the mass of water in a tea kettle when it boils?
The liquid mass is partly converted to a gas (steam, water vapor), so if this escapes, the mass is no longer there. The steam can, however, be captured and condensed, and used again (as in steam engines).
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.
Why does temperature remain constant during the boiling of water although is supplied?
The boiling water at its boiling point uses the extra energy being supplied to transform its state from liquid to gas (steam) at the rate of 540 cals per gram. Now if you have the water boiling in a pressurized vessel you can make the water boil at a higher temperature and this is used in certain applications but the temperature will remain constant at that pressure as long as there is water to be converted to steam.
How is coal converted to the energy people use?
The most useful energy that coal provides is as a fuel for combustion; we have to burn it. Burning coal creats heat we can use to boil water, turning it to steam, and then we use the steam to drive turbines to make electricity.
Why does temperature remains constant when water is heated to change into steam gas?
Because any additional heat applied after the steam has formed is converted into further expansion of volume. If the volume is contained and cannot expand (as in a boiler), the temperature will rise further and the steam is said to be super-heated.
How is nuclear converted to electricity?
First it is converted to heat. This will then usually drive some variation of a steam engine.
What is heat energy and steam energy converted to?
mechanical energy
What is Thermal energy that is converted into mechanical energy?
steam engine
How is stored chemical energy converted into thermal energy when coal is burned to make steam?

When clothes are dried in sunlightthe water found in the clothes is converted into which form?
Steam
How much does water expand when it turns to steam?
At 212 degrees Fahrenheit water expands approximately 1,700 its original volume when converted to steam.
What need to be done to a fuel to release the energy stored in it?
The process of combustion combines fuel with oxygen, to produce carbon dioxide and heat. If the fuel is burned in a boiler to produce steam, this heat energy is converted to pressure energy in the steam. The pressure energy is converted to rotating kinetic energy as the steam spins a turbine. Finally the rotating kinetic energy is converted to electric energy in the generator.

How can you convert nuclear energy into energy that you can use?
First it is converted into heat. This is then usually converted to other types of energy through a steam engine.
Why you use saturated steam in steam tracing?
If you use saturated steam, the main source of the heat is provided by the condensation of the steam at a constant temperature. The energy provided by the condensing steam is significantly more than what you can get from just changing the temperature of superheated steam. When the temperature remains constant, design calculations are also a lot easier; the temperatures stay the same (or almost the same) for the steam along the entire run and the pressure stays the same (or almost the same).
What is the working principle of steam jet ejector?
it is not based on bunoullies theorem it is based on mach number.when sonic speed of steam converted to supersonic steam by nozzle vacuum is created.
