Summary
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. ... Read More

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.

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.
