what is the defference between liqiud flow fast and liquid flow low?

it has to do with the viscosity of a fluid at different temperatures. like oil. oil comes in different thicknesses. 10w-20 10w-30 and so on. the thickess is a 90 weight gear oil and if it 20 degrees outside it wont flow just as water wont when it freezes.the thicker a fluid is and as the temperature gets colder it wont flow.

the retention times are longer for everything. The gas flow rate is the only variable decider in the speed of transit through the columns. Slower flow means slower movemnt independent of column interactions\n\nThe separation should theoretically be better for everything besides the components that don't interact at all with the column. They come out at dead/void volume anyway. The other components are better separated because the slower flow rate means they have more time to interact with the stationary phase and so the differences in elution rate become more pronounced.

8X is the slowest of the 2. Slow speeds helps to ensure your CD burner does not make any mistakes during the burning process.\n\nHope this Helps!

Both CPUs are using clock speeds at different frequencies.  The performance delta between the two processors is going to be due to the internals of the processor.\n\nThe processor may have internal components which need to tell the clock "wait, I'm still working on something" and then let it know when it is finished.  That 'wait' operation takes the same amount of cycles on a faster clock as it does on a slower clock.\n\nSo, the main factors (aside from the outside of heat and cooling) are the number of clock cycles consumed by internal components of the processor.  The more 'streamlined' the internal components of a processor (i.e. the less clock cycles they consume) the faster they perform an operation.\n\nYes, it is possible to have a processor that operates at lower clock speeds and performs just as fast as processors that operate at higher clock speeds, only because they found a way to solve a problem in less steps.

What context are you describing (or is that what you are asking)?\n\nHot water will freeze slower than cold water.  In order to freeze the water temperature must be dropped to freezing temperature, and the farther away you are from freezing, the longer it will take to 'bleed' the temperature away by any known method.\n\nI am not aware of any condition where hot water will freeze faster than cold water, assuming the water in both situations is exactly the same (i.e., not water made of different material, or with another chemical in aqueous solution), so if someone can give this example, I would be very curious to see it.\n\nPerhaps there is a situation where you can heat a liquid to convert it into gas, and then from gas directly to solid (frost formation is an example of this).  I am not sure, but this might be one approach to try getting water to go to a solid state faster when the water temperature is initially higher.  The key is you are bypassing the liquid state.\n\nAddendum:\nActually now that I think about it, I have an aswer.  If you have supercooled water, i.e. water that is below freezing, it could stay in that metastable state indefintely.  So here is a case where hot water would cool faster.  The hot water will cool down to freezing and will freeze, while the supercooled water may never turn solid.\n\nAddendum:\nWow, this link that someone below posted is interesting:\nhttp://math.ucr.edu/home/baez/physics/General/hot_water.html\n\nI was going to say that it is impossible, since water at a higher temperature would have to pass through all lower temperatures, but this article pretty much explains it (in that, well, we just don't know).  It has been observed, but there is no explanation that can be agreed upon.\n\nTo be completely pedantic, I note that most of the explanations point to what I would consider to be "experimenter's errors" in the set up of the experiments (if more dissolved gas is in hotter water, than the two water mixtures are certainly not the same, so this is an invalid experiment... if there is a 'hot top', then the experimenter did not start with a homogenious mixture, and that has to be mentioned in the experiment... if the surrounding environment is not the same, then the ambient conditions are changing which not an assumption in a traditional experiment, but rather a source of error... if evaporation is allowed than some quantifiable mass of the water is not turning solid, so this again is invalid).  The only explantation that doesn't result from a poorly set up experiment is supercooling.

uses more oil quicker. i stuck on the question please explain more

Clearly the answer is water.  The reason has to do with the 'viscosity' (viscosity = resistance to flow) of the three fluids:\nhttp://en.wikipedia.org/wiki/Viscosity\n\nWater: low viscosity ─► marble moves quickly\nSyrup and Shampoo: high viscosity ─► marble moves slowly\n\nAlso look into 'Reynolds numbers':\nhttp://en.wikipedia.org/wiki/Reynolds_number

yep, a low normal 60-80 is normal with anything under 50 slow and anything above 100 fast

Simple answer:\n\nWater is a thicker fluid (at room temperature) than acetone is.\n\nViscosity is resistance to flow, and acetone is a short chain polymer giving it its 'thin-ness'. Thus its viscosity is lower than that of good old H2O.

Pressure a higher pressure will push the molecules closer to each other so the reaction takes place faster cause the molecules colide more often.\n\nAmounts of the chemicals, will take longer as you increase each to fully react because there is more to react.\n\nConcentrations of the liquids a higher concentration will have more of the molecules to react.\n\nAnd the amount of activation energy if the amount is low the reaction will procede at a faster rate.

Water is a Newtonian fluid, meaning its shear stress is linearly proportional to rate of shearing strain. Agitation will not affect its viscosity. Pressures will not affect it either unless they are extremely high.\n\nThe viscosity of water generally decreases as temperature increases. Water at 32ºF has an absolute viscosity of 1.794 cp (centipoise). At 200ºF, its viscosity will have decreased to .305 cp.\n\nThis means that water will flow slightly more easily at higher temperatures.\n\nFor some mathematical models, check out this link:\n\nhttp://en.wikipedia.org/wiki/Temperature_dependence_of_liquid_viscosity

Fresh water evaporates faster than the solutions will.  Between the solutions it would depend on the number of particles dissolved in the water.

water freezes at 32 degrees Fahrenheit, and 0 degrees Celsius\n\nthe colder the faster

If there are bubbles of air then you will have less liquid than you are intending to have. Assuming you are calculating density via measurementof mass then the mass you get will be less than it should be for that volume of that liquid. As a result the calculated density will work out lower than it should do.

The relative differnce in gas concentrations.  Thus, if the concentrations are nearly equal, there is a slow rate.  This is true for nearly all rates, for example, if you have ice at 0C, and put it in a refrigerator at 4 C, it will take a long time for the ice (water) to become 4 C.  Thus, say 2 or 3 hours to just move 4 C.  But, if you take ice at 0 C and put it in a room thats 40 C, it'll warm 4 C within a few minutes.  The controlling element is the relative difference between the two levels.

Higher specific heat capacity liquids can absorb more heat energy per unit of liquid than lower specific heat liquids.\n\nIn most applications the higher specific heat liquid will be the liquid of choice as it can "carry away" more heat per unit volume.
