What is a small summary about The Crucible by Arthur Miller?
In the physical device called a "crucible", a small pot is heated, and golden items can be melted. Gold itself melts at a relatively low temperature, while alloying metals and impurities remain solid, and will float to the surface of the liquid gold. This allows the jeweler to skim off the dross, leaving only the pure gold, which when cooled could be fashioned into jewelry. In literature, there are several books and stories that use the crucible as a metaphor for human desires and feelings. By "heating" all of the actors to an emotional feverish pitch, the characters will reveal their flaws and inner demons, allowing the true nature of the person to be revealed.
Why must the crucible be cooled before weighing?
There are a few reasons: Safety, so individual does not get burned; a hot crucible could damage the scale; hot crucible could alter the substance being weighed; a hot crucible as the heat is released into surrounding air, it causes convection air currents when using an electronic scale than measures to multiple decimal places can give a miss reading and give the individual a larger error percentage in their experiment.
How do you weatherproof a flat screen tv?
Although there are a few TV screens that have weatherproofing kits, they tend to be very expensive to buy and to fit. The other method is to build an enclosure to protect the screen from water damage. A housing of marine plywood is a good start, with a safety glass aperture for the display. The television will generate heat so it is vital that air can move through the enclosure to keep it cooled. The ventilation holes need to be weatherproof as well of course. Remember that the enclosure must be substantial enough to support the television and must itself be properly supported.
Why didn't Shakespeare like the Jews?
During the time of Shakespeare Jews didn't live in England (they were cast out by Edward the 1st.)It is probable that Shakespeare had never seen a Jew in his life, however in 1594 a famous Jew stood for trial - Rodrigo Lopez and scholars believe that Shakespearean knowledge about Jews came from this famous trial.in 1597 Shakespeare wrote "the merchant of Venice" which besides the endemic antisemitic views of that time also portrays the Jew as human in a certain "spin" in the famous monologue"Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, senses, affections, passions; fed with the same food, hurt with the same weapons, subject to the same diseases, healed by the same means, warmed and cooled by the same winter and summer, as a Christian is? If you prick us, do we not bleed? If you tickle us, do we not laugh? If you poison us, do we not die? and if you wrong us, shall we not revenge?" 3:1which is very positive in comparison with Marlowe's (shakespear contemprour) "the Jew from Malta" - a totally antisemitic awful portray of the Jew.Shakespear Jew all in all is a complicated - human figure.
What is Julius Caesar's general legacy?
Christianity for one. up until 200AD the Romans held the cult of the divine Caesar (Divus Iulius) as their state religion.. they worshipped Caesar Clementia (clemency) the man who forgave his enemies but was betrayed by someone close to him and publicly executed. (sound familliar?) after a few tweaks it became Christianity and a lot of sectarian strife around the Empire was cooled. The first paved roads in France. (roman roads fostered trade all across Europe for centuries and were only surpassed in the 19th century with the rail system) the 365 day year. He was responsible for the final subversion of the Roman Republic (SPQR) and studying this event modern democracy's adopted a supreme court and other systems to check ambitions in the future. He was one of history's first economic reformers. (He put restrictions on slave ownership to alleviate unemployment) one of the first proponents of psycological warfare, he went to great lengths to demoralise Pompey's legions before they engaged at Pharsalus one of the first proponents of Public Relations, his communications from Gaul were celebrated all across Rome. his works are the main primary source used to teach Latin. (commentarii de bello gallicio) basically Julius Caesar was a living God. Gaius. Julius. Caesar.

Why should you use tongs rather than fingers to handle your cooled cricible and lid?
Because fingerprints can add a considerable mass to the crucible when weighing it.

Why would it be difficult to open the desiccator after its contents have cooled?
In the event that you have accidentally placed a hot sample inside a typical desicator (without stopcock), and partial vacuum build up. Plus heating don't help. One way to open the desicator is: PARTY RIBBONS or any thread like material that is fine enough and tough. Place the ribbon to the circumference of the desiccator and pull on both end so the string moves inward towards the center and break d partial vacuum.

What is sulphated ash?
The sulphated ash test is an analytical test for determining the inorganic content of a sample by weight. The sample ( usually 1g) is accurately weighed into a platinum, silica crucible that has been previously ignited, cooled and weighed. The sample in the crucible is then subjected to sulphuric acid (usually 1mL) and charred at a low temperature without causing ignition of the sample until there are no more white fumes given off. The crucible with the charred sample is then placed in a furnace (temperature is dependent on monograph but typically it can be from 600 to 900 degrees celcius) until all organic matter has been burnt off. The crucible is cooled and re-weighed. The difference in sample weights being the sulphated ash content remaining. Some monographs require the sample to be re-ashed until a constand weight has been achieved. The remaining inorganic matter is typically metal oxides from most samples.
