Hello! My name is Anders Celsius. I was born in Uppsala‚ Sweden on November 27‚ 1701. I was born into a very highly scientific and scholarly family. My grandfathers were both astronomers and my father‚ Nils Celsius‚ was an astronomy professor at the Uppsala University. Also‚ I studied at the University of Uppsala‚ became secretary of Uppsala’s scientific society‚ and succeeded my father as the professor of astronomy there in 1730. I traveled for several years to further

Anders Celsius was born in Uppsala to Nils Celsius who was a professor in astronomy. His two grandfathers were also professors’‚ one taught mathematics and the other was and astronomer. In 1732 he began his grand tour and visited almost all of the notable European observatories of the day‚ where he worked with many of the leading 18th century astronomers. Celsius went on an expedition with the French astronomer Maupertuis. The expedition was to measure the length of a degree along a meridian

------------------------------------------------- Fire Fire is the rapid oxidation of a material in the exothermic chemical process of combustion‚ releasing heat‚ light‚ and various reaction products.[1] Slower oxidative processes like rustingor digestion are not included by this definition. The flame is the visible portion of the fire. If hot enough‚ the gases may become ionized to produce plasma.[2] Depending on the substances alight‚ and any impurities outside‚ the colorof the flame and the

table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment‚ gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different elements and salts it boiled up to 74 Celsius in five minutes of boiling. Our understanding that only pure water boils up to 100 Celsius. Also‚ the longer it boils the higher the increase temperature and evaporation occurs; this recorder under data 2. The

Since 1861‚ the average temperature has increased by 0.6 Degree Celsius. Scientists believe that‚ by 2100. there would be a 4-6 Degree Celsius increase in temperature and a 5-9 centimeter sea level increase. As the temperature increases‚ ice bergs would start melting and homes of Polar Bears and Penguins will be destroyed. There will also be an increase

During the seventeenth century in England‚ outside temperatures reached so low during the winter that it is actually considered to be a “mini ice age” by scientists today. During this time‚ people were still somewhat fatalistic and believed that cold was an act of god‚ and that people should just leave it alone. That was until an alchemist named Cornelius Drebbel came along. Drebbel bet the King he could turn summer into winter by chilling the air in the Great Hall of Westminster. Drebbel did
