What does composition mean as in school?
Composition Means When You Compose A Story Or Put Something Together.
How much is1 tone steam to cubic meter?
for converting cubic meter to ton , density or specific volume is needed. specific volume unite is m3/kg. steam cubic meter/ (cubic meter/kg)= steam (kg ) /1000= tone of steam
How many kilo calories is 1 ton steam?
It depends on the temperature of the steam, which, in turn, will depend on the pressure.
What is the importance of percentage composition?
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
What is your assumption from the dryness fraction's reading is 0.504?
Steam with a dryness fraction of 0.504 consists of 50.4% steam and 49.6% water.
Is steam turning into water chemical or physical?
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
What is the highest moisture content allowed in steam turbine?
it is a composition of dryness fraction (1-x) .
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
Is water heated and changed to steam a physical or chemical change or both?
physical only, you are only changing its state, not its composition.
What kind of water is a steam?
Steam is water in the vapour (gaseous) state; Ice is water in the solid state; liquid water is water in its liquid state - but the water's composition is the same in all three states.
What conditions are needed to make ethanol from ethene and steam?
Heating a mixture of ethanol and water would produce a mixture of water vapor (steam) and ethanol vapor. Depending on the composition of the mixture, there could be more ethanol vapor than steam in the resulting gas mixture.
If you boil water and itb t turns into steam is that a chemical reaction?
Nope - it's a physical change. The chemical composition is still H2O
How will we justify that ice water steam are the three state of a substance and not different substance?
The chemical analysis show that the chemical composition of the molecule is the same.
A change in which composition of matter stays the same?
Yes. For example, water changing to steam (evaporation) is a physical change. While the water is now a gas (steam) & no longer a liquid, its chemical composition is still the same: H2O (2 atoms of hydrogen & 1 atom of oxygen)
Is water is heated and changed to steam is it a physical or chemical change?
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.
If you have steam in a test tube which condenses to moisture-is this a physical or chemical property?
You have a phase change which would indicate a physical change since the substance remains the same in composition.
Why doesn't sweet dough produce a flaky crust?
Because of its composition. Flaky crust uses steam (created from the fats used) for rising and texture, where doughs use yeast for rise, and less fat.
