Why distillation is not used often for cleaning water?
Because when water is distilled it losses all the essentials salts and minerals.
What kind of energy is light energy?
Well, you might just put it in a separate category, and call it "light energy". But it is probably better to place it in the broader category of "electromagnetic waves".
What chemicals are present in petrol?
Petrol is a mixture of Hydrocarbons (obtained from crude oil) through the process of fractional distillation. Fractional distillation basically involves heating a mixture at different temperatures to obtain individual compounds. Crude oil is not a compound, it is arbitrary mixture that contains myriad hydrocarbons. The shorter hydrocarbons will boil at the lowest temperature (shorter chain = less energy) and the longer the hydrocarbon chain gets (a general measure of the carbons in the chain) the more energy it takes to boil it. Petrol generally contains between 6 and 12 carbon chain length hydrocarbons. I can't give specific names because hydrocarbons comes in saturated, unsaturated, cyclic, aromatic, xylene forms. Read up on some Organic Chemistry to get a brief overview of these. Petrol can contain carbon chain lengths of 6 and 12 that could be anyone of those hydrocarbons mentioned above. Each has its own properties that affect the properties of petrol in general, mainly affecting energy density of the fuel. Due to double bonds, triple bonds, cyclic structures etc.
What does a solid turn into when its heated?
When a solid gains thermal energy, its atoms and/or molecules begin to move (vibrate) faster and faster as the temperature continues to increase. Eventually, the particles that make up the solid will gain enough thermal energy in order to separate into a liquid through melting or into a gas through sublimation.
Distillation and Filtration which is cheaper?
Expect simple filtration by gravity to use less energy than distillation (where you have to take the material to its gaseous state) so it will be cheaper, but if you're considering reverse osmosis (a hi-tech form of filtering) against solar-powered distillation (in a solar still), the running costs of R-O are large, the running costs of a solar still are small.
What is the advantage of simple distillation to fractional distillation?
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.
What is the difference between simple distillation and fractional distillation?
Simple distillation refers to the "simple" separation of a solid and a liquid by evaporating the liquid and collecting it after it passes through a condenser to be changed into a liquid state. Fractional distillation refers to the more complex way of separation, usually involving a liquid/liquid mixture (eg. ethanol and water). these can be separated since they both have different boiling points. When this mixture is heated the ethanol having the lowest boiling point boils off first, followed by the water. However the fractional coulomb condenses both gases back into liquid, and fall back in the flask, with time the ethanol gains enough energy to over come the fractional coulomb (this happen before the water does this since ethanol has a LOWER boiling point) and pass through the condenser, changes into a liquid and is collected.
Why don't the hydrocarbon molecules breakdown into hydrogen and carbon atoms when they are heated during fractional distillation?
Hydrocarbons do not break down into their elements when fractionally distilled because the minimum energy necessary for separating the hydrocarbons into their elements is not available from the thermal energy needed to perform fractional distillation.
What is a distillation disadvantage of fractional distillation?
One of the main sources of all types of energy is from sun.. The sources like fossil fuels, etc r gonna sure disappear some years later.. also its utilisation now also creates serious impact on life of human beings...u can c in many places were its temperature is hike... so installation of other devices for purification s a hard tiring process. so the better option s to use the available source for the purification process will be a good one. so its a advantage...

Can a compound be separated into its elements by filtration?
A compound has formed a more stable state than the elements by themselves. They released photons to the Universe in honor of this more stable configuration. Unless the "filter" is made of strands of energetic plasma, that can rip this more-stable configuration apart by supplying the lost "binding energy", no. The answer is "no", filtration cannot separate out elements.
Why can't we use solar energy for distillation?
You have a misconception here as solar energy definitely can be used to perform distillations. However for more than trivial quantities large arrays of mirrors are required to concentrate the sunlight to get high temperature needed for the process to be efficient and practical.
Why when you mix 2 elements together you can often separate them again quite easily?
Mixtures can be separated easily, liquids by distillation, gases can be made into a liquid , and then heated gently to tap the gases off ( also called distillation) solids are a little more difficult and depend on the mixture.Compounds are much harder to separate because they are chemically bonded together.They can be separated by electrolysis but this takes a large amount of energy.

Why isn't alcohol production from biomass energy efficient?
distillation. Boiling the solution requires more energy than the energy content of the ethanol present.
Reactive distillation process?
Reactive distillation is a process where the chemical reactor is also the still. Separation of the product from the reaction mixture does not need a separate distillation step, which saves energy (for heating) and materials.This technique is especially useful for equilibrium-limited reactions such as esterification and ester hydrolysisreactions. Conversion can be increased far beyond what is expected by the equilibrium due to the continuous removal of reaction products from the reactive zone. This helps reduce capital and investment costs and may be important for sustainable development due to a lower consumption of resources.

How is petroleum made into energy?
Typically by burning it (oxidation), to release the chemical energy stored in the carbon-hydrogen bonds of its molecules. The process ranges from simple burning (kerosene lamps and jet engines) to internal combustion, or explosion, of gasoline or diesel fuel (cars and trucks). The various components of petroleum are separated by fractional distillation: vaporizing the oil and recondensing the components, such as kerosene, naphtha, propane, gasoline, and other fuel oils.
