Actually if you place your hand into steam, you WILL get burnt. What you are probably thinking of is placing your hand into the condensate of the steam that appears like a cloud. You can place your hand into that because it has to cool to a much lower temperature before it begins to condense. True steam is actually a colorless (at least in the wavelengths we can see with our human eyes) gas and is invisible to us.

How is coal used to create power?
put the coal in a furnace and smelt stuffA more useful answerCoal is burnt to make heat, the heat is used to heat water, the water turns to steam and the steam turns a turbine that runs a generator. In ole ships the turbine or steam engine ran the propellers directly.
How can you steam?
To steam food, you typically place it in a steam basket or on a rack over boiling water, then cover the pot with a lid to trap the steam. The steam cooks the food gently and helps it retain its nutrients and flavors without submerging it in water. Steam can be used to cook a variety of foods such as vegetables, seafood, and dumplings.
Why is oil burnt in power stations?
Oil is burned in power stations to produce heat, which is used to generate steam. This steam then drives turbines connected to generators, producing electricity. Oil is used because it is a relatively cheap and reliable source of energy that can be easily transported and stored.
Is boiling water to make steam a physical change?
Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.
Is it possible to boil water by passing steam at atmospheric pressure?
No, passing steam at atmospheric pressure will not cause water to boil. Boiling occurs when the liquid reaches its boiling point temperature and vapor pressure overcomes the atmospheric pressure. Generally, steam at atmospheric pressure will only cause the water to heat up and potentially evaporate faster.
How do trains run on coal?
Only (some) steam engines used coal. It was burnt in a boiler to heat water to steam.
How is fossil fuel used to create electricity?
Coal is burnt to boil water into steam steam is then used to drive turbines that are connected to generators that make electricity
How do you make steam without water?
You don't.
How is hydrogen used to generate electricity?
Hydrogen is burnt to boil water. The steam spins the electric generators, as in a fossil fuel (coal, oil and natural gas) power station, except without causing global warming, as the only emission is water.
What makes steam-fired?
When water heats up to the point where it starts to boil, steam will descend from the water. So, water and high temperatures create steam. But, since other liquids also can create steam, I would say that if you boil a common liquid you will get steam.
Is steam an element compound heterogeneous mixture or a solution?
Steam is a gaseous compound, ie. vaporous water eventually mixed (homogenously) with others like in air. However a heterogenous mixture of tiny water dropplets, which can be seen coming off a container with boiling water, is (erroneously) called steam, this is a heterogenous mixture of air (gas) and liquid (water). Real steam is invisible, and far more dangerous to get burnt from!
What to do when you get burnt by a steam cleaner?
this burn is propably 1st dagree- superfical -put under cold water for 10-20min -put a ice pack on
How does a coal power plant work?
Coal is burnt to produce heat to make water boil. The steam drives a turbine which turns a generator to make electricity.
What are the steps taken to produce electricity using fossil fuels?
Fossil fuel (coal) is burnt in furnaces. The heat produced turns water into steam. The steam is fed through steam turbine generators. It is these generators that produce electricity. This electricity is fed onto the national grid.
What fuel is used in steam trains?
Coal was burnt in the furnace. This heated water in the boiler to high temperatures. The steam was used to operate the pistons and to drive the train.
How does coal produce energy?
Coal produces energy through combustion where heat is generated by burning coal in a furnace. The heat produced converts water into steam which drives a turbine connected to a generator, producing electricity. Coal is a fossil fuel that releases stored energy when burned, making it a primary source for electricity generation in many countries.
How does gas power electricity?
The most popular method of generating electricty is, to use a steam turbine to drive a generator. The fuel used, is burnt to produce heat. The heat is used to make steam, by boiling water. So gas is burnt to produce heat, which boils water to make steam, which spins a turbine connected to a generator. Gas could also be used in an internal combustion engine, which is connected to a generator. This is normally used for small scale production, not on a national grid.
