The full strength 1M HCl acid had a pH level of 3.12 (Table 3.1). Sample A2 to A4 remained in the pH 3 level‚ while sample A5 and A6 had a pH range of 4 (Table 3.1). The pH level for 1M HCl dilutions slightly increased between each sample (Table 3.1). The diluted solutions of 1 M NaOH showed a few unexpected results. The original solution of 1 M NaOH was at a pH level of 11.50 (Table 3.1). However‚ the pH of sample B2 increased to 12.81 (Table 3.1). The remaining samples had a decreasing pH pattern

Global Atmospheric Circulation This essay will describe patterns of atmospheric heating and circulation. When the surface air reaches the Equator‚ it gets heated and rises to the top of the troposphere‚ where it spreads back toward the poles. When it gets to the poles‚ it descends back to the surface again to complete the cycle. The heat of the Sun causes water to evaporate from lakes‚ rivers and oceans‚ as well as from the leaves of plants called (transpiration). But this water

* What is the greenhouse effect‚ and how does it work? The greenhouse effect is when the short wave lengths of visible light from the son pass through a transparent medium. They are then absorbed but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium. The Greenhouse Effect is when there are various gases in the atmosphere‚ such as carbon dioxide and even water vapor that traps the sun ’s energy‚ or heat‚ inside. When unable

Global and China Silica (White Carbon Black) Industry Report‚ 2014-2017 Summary China‚ the world’s largest silica producer‚ had silica capacity of 2.20 million tons in 2013‚ slowing to a year-on-year increase of 8.1% and accounting for 60% of global capacity‚ of which 2.079 million tons were precipitated silica and 118‚000 tons fumed silica‚ rising by 7.44% and 21.15% from a year earlier‚ respectively. Ever-increasing silica capacity is attributed mainly to the increase in downstream demand‚ especially

Breaking a Ruler with Atmospheric Pressure Introduction In this experiment‚ I will try to use air pressure‚ along with some sheets of newspaper‚ to attempt to break a ruler. Air pressure is the weight of the atmosphere pressing down on the earth. A device called a barometer measures it in units called millibars. Most barometers use mercury in a glass column‚ like a thermometer‚ to measure the change in air pressure. I came up with this idea from when I read in a book about how some kids tried to

Atmospherics is a technique of how stores or restaurants used to make customers be less rational in their buying spree. In Rushkoff’s reading‚ “Atmospherics”‚ it describes the behaviors of customer in the designs of atmospheric in the store. The author introduces several techniques which implied to the strategy of atmospheric‚ such as floor plan‚ temperature‚ and lighting. According to Rushkoff’s idea of atmospheric‚ atmospherics have several designs for the promotion in store or restaurant. For

No; the experiment was not successful‚ because it did not show the correct fluorescence gradation of the serial dilution of the DNA concentration. As shown by the picture‚ only the first drop of the DNA/EtBr mixture for the DNA standards fluoresce brightly under the UV light‚ while the other spots for both the DNA standards and the unknown DNA standards were all dimly fluoresce. This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA

Modern life has improved since the 1950’s. This period is quite memorable for a lot of things‚ the more famous of which being the flared trousers Elvis Presley‚ the icon of rock and roll and pop music‚ brought into style. There were many positives and negatives of living in the 1950’s‚ but it is clear that modern life has been a great step forward from those times. Firstly‚ the general aspects of life such as money‚ crime‚ racism and drugs‚ were viewed very differently in the past. Secondly life
