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.

What happens when water changes from a liquid into a gas?
Evaporation
What is the steam point of the Celsius scale?
at 100 degrees liquid water will go to steam and steam will go to liquid water
Is steam a solid liquid or gas?
It is a gas.
What does liquid water become when it absorbs enough heat?
It becomes steam SIMPLE
What are the three types of geothermal energy?
Dry Steam Power Plant : generates power directly from the steam from inside the earth.Flash Steam Power Plant : Flash steam plants use waters at temperatures greater than 360F. As this hot water flows up, it is collected in a flash tank where drop in pressure causes the liquid to boil into steam. The steam is then used to run turbines which in turn generate power. The condensed steam is returned to the reservoir.Binary Steam Power Plant : This type of plant uses high temperature geothermal water to heat another liquid which has a lower boiling point than water.
Why do we get a more severe burn from steam at 100 Degree Celsius than from an equal amount Of water at the same temperature?
In order to turn from water to steam, the liquid must absorb a large amount of energy. Even though they may be the same temperature, this extra energy means the steam can cause a more severe burn.
Why steam at 100 degree centigrade produces more severe burns then boiling water at 100 degree centigrade?
Steam has enough kinetic energy to leave the liquid water that is boiling, so it's greater amount of energy results in more severe burns than boiling water, which has a lower amount of energy.
Is steam in the liquid state?
Steam doesn't cool off liquids because it is the release of thermal energy from the water, and that is why, it is therefore hot. If the steam is coming off the liquid itself, it is heat being released by the liquid, but the liquid is not necessarily getting cooler. Think of water boiling on a stove. There may be plenty of steam coming off the water, but the water continues to boil. Subjecting a cool liquid to steam will certainly not cool the liquid.
Which contains more heat energy water at 373K or steam at 373K Why?
it is steam because it occupies latent heat of fusion ..............
Solid ice will change to liquid water and then to gaseous steam when you add what?
Energy because energy can be used as heat.
When do water molecules have the most greatest amount of energy?
Steam at 100C
How do you use steam tables?
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
Why steam is more dangerous than boiling water?
steam scalds are more serious than boiling water scalds because steam when condenses onto the more cooler skin, it loses latent heat of vaporization (to become water at 100 degrees Celsius) also it loses thermal capacity to become equal to the temperature of the skin (37 degrees Celsius). boiling water loses only thermal capacity as it cools down to 37 degrees Celsius from 100 degree Celsius.
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

Why would a burn by 1 gram of steam do more damage than a burn caused by 1 gram of water at the same temperature?
It requires energy to change the state of water from liquid (water) to gas (steam), so even thought they are at the same temperature, the same amount (1 gram) of steam holds more energy than 1 gram of liquid water at the same temperature. If the steam came in contact with a person's skin, it would lose energy, some of it absorbed by the person (causing damage), and it will not reduce temperature until it is condensed, because all of the energy lost was due to the state change.
Why is the steam obtained more than a thousand times larger then the amount of water boiled?
Steam is water, or another liquid, in a gaseous state. As a substance heats and changes stage from liquid to gas, the particles of liquid begin moving more rapidly and spread out, thus expanding to 1,000 times the original amount.
