H.W 4 GSC125-01 - Essay Example Answer: According to the second law of thermodynamics, heat flows in response to a temperature gradient. Heat flows from a high-temperature region toward low-temperature region to remove the existing gradient. Heat is transferred by the processes of conduction, convection, radiation and latent heating (phase transition of water). Answer: On a global annual average basis, radiational heating of earth’s surface is greater than radiational cooling and radiational cooling of the atmosphere is greater than radiational heating. However, due to the formation of temperature gradient, heat is transported from warmer earth’s surface to the cooler atmosphere through processes of latent heating and sensible heating cooling the earth’s surface. Radiation is the principal means by which heat enters and escapes from the planet to space maintaining a habitable environment on earth. Answer: If the temperature falls below freezing, bridge will freeze more quickly than the road surface. Compared to road surface, bridge is exposed to air from all sides resulting in rapid heat loss. Additionally, the heat underneath the road keeps it warm enough extending the time duration of heat loss. The bridge material (mostly steel or concrete) is also a good conductor of heat, whereas road surface material (asphalt) is an insulator of heat. For these reasons, a traffic sign along an Ohio highway warns motorists that a bridge freezes before the road surface. Answer: Both Fahrenheit and Celsius are useful temperature scales for measuring temperature and are based upon the reproducible phase changes in water. On Celsius scale, freezing point of water is 0Â °C and boiling point is 100Â °C. On Fahrenheit temperature scale, water freezes at 32Â °F and boils at 212Â °F. Thus, the Celsius scale is more convenient to use as a 100 degree interval separates the freezing and boiling points of pure water at sea level. Compared to Celsius, Fahrenheit scale is more

Paraphrasing - Essay Example Reports from eyewitnesses were recorded that a cloud of gas settled over and gradually moved through the shanty towns (Shastri, 1985). However, diffusion of this gas cloud was prevented by atmospheric inversion and low-wind speed. When the gas cleared on the dawn of December 4th, the affected individuals were either dead or injured. According to statistics, this is considered as one of the worst industrial disasters to happen; resulting to approximately 3,787 deaths and 558,125 injuries. This outstanding rate of fatalities did not stop but persisted for months causing further harm. Approximately 50,000 people were estimated to suffer from the long-term health effects. Moreover, nine years after the fatality, more than a thousand residents continued to experience health issues which may be linked to the accident. Examples of such health issues are corneal opacities, numbness, early cataracts, Post traumatic stress disorder, Impairment of memory, finer motor skills, and chronic bronchi tis (Dhara & Kriebel, 1993). After the tragedy, Union Carbide India Limited with the permission of the Indian government cleaned up the area until 1998. Union Carbide India Limited also donated $2 million to the Prime Minister’s Relief Fund, $5 million to the Indian Red Cross, and shared all information concerning methylisocyanate with the Indian government. In the year 1998, the Madhya Pradesh State Government took over Union Carbide India Limited and assumed responsibility. Five years later after the tragedy, the Supreme Court of India ordered Union Carbide India Limited to pay $470 million to the Indian government; the amount was paid in full ten days later. Moreover, the court ordered the Indian government to purchase medical insurance policy to cover 100,000 affected people. In the year 2004, the Supreme Court of India ordered the Government to give the remaining
