Simple and Fractional Distillation Experiment

If the flask were too full, the distillation process would also be slow as there would be little surface area for rapid evaporation of the boiling liquid.Sometimes mixtures may boil off a vapor which has the same ratio of constituents as the liquid mixture which means the chemical composition stays the same in both the liquid and vapour form.Vapourization involves the exciting of the atoms and as they reach the surface of the liquid they must overcome the pressure and attractive forces to become vapour.The cooling water within the condenser must enter to bottom and exit the top because the water must be circulating and the theory of condensing requires a vapour to cool to become liquid.It is dangerous to heat a liquid in a distilling app...

The Liquid Ring Pump

The vapour pressure of the sealant liquid into the Liquid ring pump plays an important role in determining the pump capacity.The liquid ring pump must then be partially filled with a liquid which will act as the sealant and results in forming a vacuum.The liquid ring pump operates as a vacuum pump using liquid as a compressing agent.This will cause the impeller blades closest to the wall to be completely submerged in the liquid sealant and the impeller blades furthest away from the wall create a void space with the liquid ring.This creates a suction force which draws gaseous fluid into the pump inlet, as the impeller carries on rotating anti-clockwise from the bottom to the top the liquid is forced closer to the impeller compressing the ...

Factors affecting the rate of Cooling Essay

For example: when the surface area increases the rate of cooling decreases and when the surface area decreases the rate of cooling increases.Therefore it is clear through my results, that rate of cooling and surface area, are directly proportional to each other when using water.One of main problem was that I had to estimate how much water to put into the beaker before heating; this was not easy as the water evaporated off and on several occasions we were left with not enough liquid in the beaker.This is because there is not much energy left in the liquid.To keep an accurate measurement I will use the same thermometer and end the experiment when the liquid reaches 50oC.

Basic oxygen steelmaking

In addition, solid scrap does not remain within the vessel after converting it to liquid.And with the fulfillment of these needs, new processes will develop that will continue to improve the way steel is produced using oxygen.Like the bottom-blown processes, the combined blowing processes suffer from the need to change out the bottom refractories and tuyeres at a greater rate than the other refractories.This modified top-blown configuration results in a lower operating cost due to stirring of the liquid steel from the bottom.They also suffer from the top-blown process’s need for larger vertical space due to the oxygen lance height.

Sulphide solubility in magma

The Nernst coefficient of partitioning, arranged for iron substitution is the ratio of the products of the % (per cent) weights of the elements substituted.Leaving the mantle, and entering the crust of the earth, the melts can either be intrusive or extrusive, yet the fundamental pressure temperature relation for sulphide solubility, from mantle to the crust in liquid state, remains the same.The increase in sulphur content with increase temperature is reinforced by the experiments of Haughton et al 1974 and Shima and Naldrett 1975, for which, although the figures are of different nature for direct comparison, the fact remains that the sulphur content actually increases with temperature, making this a control of sulphur solubility in the ...

Techniques for Cell Preservation

Some types of liquid remain uncrystallized in these conditions depending on there properties and retain the physical properties of a liquid (Wowk, 2010).When the liquid is cooled sufficiently it becomes viscous in a glass like state or a non moving liquid, molecular diffusion stops and ice formation is insignificant.There are three main approaches to vitrification: ultra-rapid cooling, pre-freeze the addition of cryoprotective agents, freeze the cryoprotective agent during slow cooling.To eliminate this problem the solution is not to drastically reduce the cooling rate as if the cooling rate is slow damage can occur as complete dehydration takes place and the physical strain caused to the cell can cause damage (Ryan, n.d.).When the solut...

Energy and States of Matter Essay

Cooling Curve Cooling curve is a graphical representation of the changes of states of substances as heat is uniformly removed from it.From our basic chemistry, we taught about the change of state or phase of matter wherein soli becomes liquid and liquid turns to gas and vice versa.As oppose to supercooling, superheating also occurs where liquid is heated to a temperature above its boiling point without evaporation.At t2 – t3, the average KE of the liquid particles decreases and the temperature reaches low level until t3 where the liquid starts to solidify.This time, the amount of liquid decreases and the amount of solid increases until reaching t4 when sufficient heat has been removed thus converting all the liquid into solid.

The effects of subcooling and superheating in refrigeration system Essay

As the cool refrigerant vapor proceeds through the evaporator, extra heat is received to superheat the vapor.[2] Prof. T. Sundararajan and Prof. J.M.If the subcooling is caused by a heat-transfer method external to the refrigeration cycle, the refrigerant effect of the system is increased because the subcooled liquid has less enthalpy than the saturated liquid.Accomplished subcooling is by refrigerating the liquid line of the system, using a higher temperature system.The last thing to be mentioned, the more effort is needed to superheat a refrigerant by increasing the evaporator load, to remove its liquid, in greater extent the power input of the compressor would increase.

The Physics of Cooling Techniques

This method can also be used to cool solid objects, but the most drastic cooling in the fractions of a kelvin range are generally accomplished for low-density gases that have already been greatly cooled (around 3-4 K) .Vapor-compression refrigeration and thermoelectric cooling are macroscopic cooling methods, as these methods can effectively cool a large amount of a substance or some other relatively large object.First, the sample to be cooled (typically a gas) is allowed to touch a cold reservoir (which has a constant temperature of around 3-4 K, and is often liquid Helium), and a magnetic field is induced in the region of the sample.The most commonly used method of cooling is with vapor-compression cycles, because it is fairly easy to ...

Investigation into the Importance of Titan

It would appear that Titan – the only body in the Solar System other than Earth to have a ‘thick’ nitrogen atmosphere – is one of the prime candidates for exploration and investigation into the development of the early Earth.Ice has a higher albedo than water and if a large enough hole was made the decreased albedo could have caused a runaway melt.If that is the case, it could be possible that life developed on Titan before it became frozen and, if it did, it may still persist deep in Titan’s interior.Carl Sagan, for instance, has speculated that on extremely cold worlds where water is frozen, liquid ammonia may act as the necessary solvent.7 It is known that Titan is comprised mostly of ice, but early in its existence, when it resided i...

The aim of this experiment Essay

This supports my expectations and I conclude the experiment as being successful.The aim of this experiment is to find out if a steaming cup of coffee stays warm longer when leaving it untouched, or pouring cold milk into it Theory Physics informs us that large quantities of liquid take longer to cool than smaller quantities.The only major error that may have occurred is the parallax error.As the table of results shows; the beaker in which the milk was poured right after the coffee was added (beaker A), meaning it contained more liquid during the procedure of going up to the door and back, did indeed stay warmer.This may have happened during the taking down of readings from the thermometers, although great care was taken to avoid this.
