Tiziano Vecelli - Essay Example According to the essay "According to the research findings" findings, at the young age of 12, he was sent to apprentice as an artist under Gentille Bellini and later Giovanni Bellini who were the masters of art at that time. After Giovanni’s death, he ascended to be the king of painting in Italy, accumulating crowns amounting to 20 and being exempted from paying taxes for his unique talent. He was the undisputed master of painting in the Venetian painting school for 60 years. His final 26 years were spent for service to Phillip II where he was a portrait artist, and where his unique attribute of keeping paintings for long periods and retouching them from time to time was discovered. He died of fever in 1576 during the Venice plague. Some of the most famous paintings he did include The Assumption of the Virgin and The Venus of Urbino wherein this discussion will evaluate both. The Venus of Urbino painting is oil on canvas measuring 119.2 by 165.5 centimeters on a landscape plan . It is estimated to have been done around 1538 as a gift from the Duke of Urbino Guidobaldo to his wife. According to â€Å"Venus of Urbino by Titan† (2013), it represented eroticism, motherhood, and fidelity. The painting is that of a young maiden in her nude lying on her back facing the foreground. She lies on a maroon bed with dark patterns covered in a white sheet. On her right palm, she clutches a bouquet and her face is calm with bright eyes. Her golden hair, plaited at the ends straddles over her right should and her breasts point upwards and outwards from each other.

Impact of a water Jet laboratory - Lab Report Example The term molar mass of a given substance is often used to refer to the mass of one mol of a substance (Computer-Based Laboratory, 2007). In mathematical terms, it is often expressed as an average molecular mass of molecules in the given substance when multiplied by Avogadro’s constant often approximated as 6.022Ãâ€"1023. It can be shown molar mass = (1/6.022) Ãâ€"10-23g/u) Ãâ€" (6.022Ãâ€"1023/mol) Ãâ€" average molecular mass (Lide, 2005).This experiment was set up to use the freezing point depression to determine the molecular mass of benzoic acid. This was possible by first determining the freezing point of pure lauric acid and lauric- benzoic mixture, then calculating the molality of solution and the moles of benzoic acid as shown below. In this lab Experiment the apparatus and materials used included Lab Quest , Lab Quest App Temperature Probe, two 18 Ãâ€" 150 mm test tubes 400 mL beaker, ring stand, paper towel or tissue 4 – 1, Lab Quest 4, lauric acid, CH3(CH2)10COOH lauric acid-benzoic acid mixture hot water bath and the utility clamp. In this experiment the procedure was as follow. The initial step involved obtaining and wearing goggles. This was followed by connecting the Temperature Probe to Lab Quest and choosing New from the File menu. For the case where one had an older sensor that does not auto-ID, manually, he/she had to set up the sensor. The next step involved tapping the rate on the Meter screen, then changing the data-collection rate to 1 sample/second and the data-collection length to 600 seconds. This was part one of the experiment in which one had to determine the Freezing Temperature of Pure Lauric Acid. After this part, the next procedure was to add about 300 mL of tap water with a temperature of 20–25 °C to a 400 mL beaker and then placing the beaker on the base of the ring stand. The utility clamp was then used to obtain a test tube containing hot, melted lauric acid from the instructor while making sure
