∙ 12y agoThis is simply a Grade 10 Physics question. It is all about "Latent Heat of Fusion" and "Latent Heat of Vaporisation" LH of fusion is about 80 Calories per gram of Water. LH of Vaporisation is 540 Calories per gram of water. Clearly more heat energy is needed to vaporise water, than to melt the ice. That is if the ice is at 0 centigrade, and the water is at 100 centigrade. This explains why Steam is so powerful. It has 540 calories of heat energy to give up before it reverts back to a liquid. If steam is heated above 100 centigrade(superheated) it can give a great deal more energy per gram.

Why does water stay at the same temp after it starts to boil?
It takes a certain energy to convert water to steam. Any additional energy you supply to the water, as heat, will be taken away by water converting to steam. The maximum temperature of a liquid is its boiling point so water shows constant maximum temperature 100o Celsius (if it is pure).
Is steam a fuel?
No. it is an energy repository. Fuels of various kinds are used to heat water into steam. the steam has more energy than the water.
How do generator convert mechanical energy to electrical energy?
Yes,the mechanical energy of steam can turn the shaft of a generator thru the steam turbine in which the steam acts on its blade to produce rotational motion to transform mechanical energy. Yes, the mechanical energy of steam can turn the shaft of a generator thru steam turbine as the driver, because the steam will acts on the tubine blade to produce rotational motion to transform mechanical energy and elctrical energy as well.
Which has the most energy particles in steam particles in liquid water particles in ice or particles in freezing water?
The particles have most energy in particles in steam. In a gas. the particles move more freely, Therefore, there is more energy in the steam. :D LOL
What is the work done by 9.00 of water when it is all boiled to steam at 100?
Not enough information to answer. Water does not do work when transformed into steam. Once it exists as steam, work can be done as it converts back to water. You will always get less out than you put in. The energy you put in is called the enthalpy of vaporization, (delta H), is also called heat of vaporization or heat of evaporation. The energy required to transform water from a liquid into a gas at atmospheric pressure is 40.68 kilojoules per mole 2260 kilojoules per kilogram. Energy is the ability to do work. Creating steam requires energy. Water does not do work when transformed into steam. Steam, after it is created, can do work and in the normal steam engine, it is then converted back to water. That process involves a few basic issues such as pressure, temperature change and entropy which are not available with the data provided.
Converting thermal energy to mechanical energy?
steam engine? Carnot cycle heat engine?
How is the steam used to produce electricity?
A 300 grams of water takes about 90 seconds to boil in a 2 kW kettle, so that is 2000 watts x 90 seconds which is 180,000 Joules of energy. But to convert that water completely into steam requires an extra 300x550x4.2 Joules, which is nearly 700,000 Joules. So converting it to steam takes 4-5 times as much energy as boiling it. That is why it takes a while for a kettle to boil dry.
How coal energy changed into mechanical energy?
By burning the coal. The stored chemical eneregy is converted to heat energy. That may be used to create steam. Expanding steam pushes a piston or turbine, converting the heat energy to mechanical energy.
If you have a liter of water at 50 degrees celsius sea level You heat the water so that you apply 100000 calories About how much of the water will boil Express your answer in grams?
To raise 1000 grams of water from 50 to 100 degrees requires 50 degrees x 1000 grams of heat, so the answer is 50,000 calories. Water at 100 degrees requires an additional 550 calories to convert 1 gram fully into steam. Therefore the remaining 50,000 calories can convert 50,000/550 grams into steam. So 90.9 grams become steam, and that's the answer.
What is the process of converting the chemical energy in fuels to electrical energy?
A simple answer is that fossil fuels are burnt. The heat is used to produce steam which drives mechanical turbines and dynamos, which then produce electricity.
What is in steam energy?
inside steam is tiny particals that is called steam energy this steam energy are a type of energy used in factorys
What is the process of converting the chemical energy in fossil fuels to electrical energy?
A simple answer is that fossil fuels are burnt. The heat is used to produce steam which drives mechanical turbines and dynamos, which then produce electricity.
State why you need coal to generate electricity?
Electricity is made by converting some form of energy into electricity. Coal is used to heat water in a boiler to make steam. The steam pressure rotates a turbine to power a generator.
What is deifference between steam engene and electric engine?
A steam engine requires water to be heated to produce steam. This steam is used in pistons to produce movement, as in a steam train. An electric engine can produce the same energy, as in an electric car, and is far less bulky than a steam engine.
How much heat energy will be required to lower the temperature of 2.67kg of steam from 282 degrees Celsius to 105 degrees Celsius?
You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.
Is steam energy?
Yes. Steam is an example of thermal energy.
What is the steam energy particle called?
While some forms of energy can be considered as either particle or wave, steam is not one of those. The energy of steam comes from it expansion. There is no steam energy particle.
