Tin Melting Experiment 3-8-11 Group 6 Summary This experiment was conducted to identify the melting point of pure Tin. In order to find that, a ceramic crucible that contained Tin was heated in the furnace up to 400C. 400C is considerably above the estimated melting point of pure Tin…
Sand was already there in the can. A thermocouple sheath made of stainless steel was also introduced into it exactly quarter of an inch above the crucible’s base. The isolation was created with a glass fiber that decelerated the cooling process. The experiment used this time to note the data. He noticed the alteration of temperature with respect to time. Until the temperature of Tin reached 150C, temperature was noted several times at an interval of 5 seconds. 150C is essentially 10C above the freezing point of Tin. This was done so as to ensure that the thermocouple sheath does not get frozen. Once the data was completely collected, the Tin cooling curve was developed using the information of temperature versus time. Abstract This experiment was intended to find out Tin’s melting point for which, a ceramic crucible that contained Tin was heated in a furnace enough to get the temperature above Tin’s estimated melting point. The molten Tin was shifted to the coffee can filled with sand. A thermocouple sheath was placed into the molten Tin and was isolated with a glass fiber. The cooling process was slowed down due to that and the experimenter noted the data meanwhile. Finally, with the help of data of temperature alteration with time, the Tin cooling curve was formulated. ...

When the material is pulled, one would be able to establish the strength of the material. In this regard, tensile testing can help one to develop an insight into various substances. Whenever one continues to pull on a material, the material will break hence one would get a recommendable profile of tensile.
3. Add 1 ml of starch indicator and 0.05 ml of 0.1 M EDTA solution from the Chemical Shelf to the same 250 ml beaker. This drop of EDTA solution is to minimize the effects of trace quantities of metal ion impurities that would cause spurious effects on the reaction.
Since 19th century scientists were aware of some unique identity of an individual which distinguish from others, like finger prints. In 1970, DNA was established as key element in human life and which makes individual as unique creature. Variability in DNA sequences among individual to individual have attracted forensic experts to develop technique based on DNA to identify individual or criminal similar to finger prints.
ADH stands for anti diuretic hormone, it is a peptide hormone which is produced by hypothalamus. Hypothalamus is a very important part of the brain and its function is to make sure that it carries out the function of homeostasis effectively. Functions of homeostasis include maintaining the body temperature, maintaining the write blood pressure level in the body etc, so it can be said that the hypothalamus is an integral part of our body.
ich falls within the theoretical range of 0.35 – 0.67 depending on the class of pine (which in this case is near the value of kind radiata at 0.48). Similarly, the experimental density of oak which is 0.75 g/ml is well within 0.6 – 0.9 and closest to the true values 0.74,
1. E. coli is in competition with S. euglensis at a temperature of 20-35 degrees and a pH of 6-7.5. E. coli is also in competition with N. atol at a temperature of 20-30 degrees and a pH of 4.5 -6.5. P.
In which case, the slope of the position time graph was compared against the average velocity obtained from the velocity time graph.
From the results attached, the slopes found in the position versus time graphs are reasonably close to the average velocities with
o calibrate the pressure transducer and then perform an uncertainty analysis and compare your pressure transducer calibration to the manufacturer’s calibration.
1. Excite the pressure transducer, with a voltage of 10v. The figure above had J17 and J18 as AO (Analog Out). It
