Effect Of Temperature On Rate Of Reaction
565 wordsEffect of temperature on RUN rate Daniel Amir eh 10-3 Khalil KarajehFactors affecting rate of reaction: Surface area - as we increase surface area, we increase the reaction rate. The more the collisions the faster the reaction. Concentration - as we increase concentration we increase the reaction rate. In reaction with between gases, increasing the pressure, increase the reaction rate. Temperature - as we increase the temperature, we increase the reaction rate. Raising the temperature makes part...

Map Consequences Of Global Warming
591 wordsGlobal warming is an event that will affect many people and animals all over the world. Humans will be affected the most due to global warming due to things like temperature increase. Many people believe that global warming began since the industrial revolution during the 18th century. During this time heat-trapping gases began to load in the atmosphere, gases such as carbon dioxide and methane. Global warming will have many negative consequences to humans, animals, and even plants. In the artic...

Global Climate Change Climate Change
2,024 wordsGlobal Climate Change Climate change is not a new concept; in fact there is evidence of major climate changes throughout the earth's history. However since the industrial revolution and especially since world war two, there has been an unprecedented change in the earth's atmosphere (Gates 4). As of March 1999, scientists reported the construction of a thousand-year record of the average temperature on earth. The results of their study concluded that a nine hundred-year cooling trend has been dec...

Green House Gase In The Atmosphere
2,060 wordsGREEN HOUSE EFFECT INTRODUCTION In temperate countries some economically important plants that cannot grow outside at a very low temperature during the winter are grown in glass-walled & glass-roofed growth chambers (known as glass houses) exposed to sunlight. Glass houses are also used in sub tropical regions during winter months & relatively cold high altitude for high value horticultural annual crops including flowers on a commercial scale as well as for research work especially for breeding ...

Temperature The Viscosity Of The Material
1,226 wordsProcesses for cleaner and more efficient energy generation from feed stocks such as coals, l ignites, pets, and waste liquors use fluidized beds that are operated at high temperatures and pressures. These processes involve systems that are multi-phase and have complex chemical reactions. Research work has tackled a number of aspects, including mechanical engineering aspects of the reactors, reaction chemistry and products, characterization and physical properties of the ash, fouling by ash depos...

Effect Of Temperature On The Enzyme Catalase
1,778 wordsTo investigate the effect of temperature on the enzyme Catalase. INTRODUCTION The aim of this experiment is to determine the effects of varying temperatures on enzyme (Catalase). We will conclude the experiment by establishing the enzymes optimum temperature (the temperature at which it works best at). We will also carry out some simple experiments using the substrate Hydrogen Peroxide. Hydrogen Peroxide + Catalase -- Water + Oxygen 2 HO -- - HO + O + heat PLAN The aim of this experiment is to d...

Average Global Surface Temperature
1,447 wordsAN INTRODUCTION According to the National Academy of Sciences, the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. Th...

Effect Of Increased Amounts Of Carbon Dioxide
934 wordsThroughout the world, the presence of particular diseases and other threats to human health depend largely on the local climate. Extreme variation in temperature can directly, and indirectly, cause the loss of human life. The threat of a gradual increase in temperature could be catastrophic to the world, as we know it. As recently as 1999, a heat wave killed more than 250 people in Chicago alone (Union of Concerned Scientists). Many right off such an event as a natural disaster. However, scienti...

Main Causes Of The Greenhouse Effect
707 wordsThe difference between Ozone Depletion and Global Warming Ozone Depletion The Ozone Layer is a region of the atmosphere from 19 to 48 km (12 to 30 mi) above the Earth's surface. Scientists were concerned when they discovered in the 1970's that chemicals called chlorofluorocarbons, or CFCs long used as refrigerants and as aerosol spray propellants posed a possible threat to the ozone layer. These chlorine-containing chemicals rise and are broken down by sunlight. The chlorine reacts with and dest...

Heat Loss From The Body
2,341 wordsAt different environmental conditions, the internal parts of the body are maintained at a constant temperature. These internal parts are together referred to as the body core. A layer of fatty tissue under the skin surrounds the core, fat is a good insulator of heat and slows down heat exchange between the core and the environment. In other words, the fat layer acts like a blanket around the body. Humans are endothermic and strive to maintain a constant body temperature regardless of the tempera...

Lesson The Global Warming Trend
622 words"Man did not weave the web of life- he is merely a strand in it. Whatever he does to the web, he does to himself". Chief Seattle, 1854 Since the mid-1800's, human activities- chiefly the burning of fossil fuels (coal, oil and natural gases) and the clearing of land- have increased the amounts of heat trapping atmospheric gases. Most of the burning takes place in automobiles, electric power plants and industrial facilities. The clearing of land reduces the amount of carbon dioxide that trees and ...

Due To The Increase In Man's Activities
469 wordsThe Green House effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere trap energy from the sun. These gases are transparent to the radiation from the sun, but opaque to outgoing radiation by the Earth. This is a natural phenomenon responsible for maintenance of the temperature which makes life possible. Without such a phenomenon our planet would experience extreme temperatures just like on the Moon. However, due to the increase in man's activities, ...

Rates Of Reaction Increasing The Temperature
1,387 wordsAn Investigation into the factors affecting the rate of reaction between magnesium and hydrochloric acid Planning Hypothesis I predict that as the temperature increases, the speed of the reaction will increase therefore the gas will be produced faster. I believe this because most chemical reactions happen faster when the temperature is higher. At higher temperatures molecules mover around faster, which makes it easier for them to react together. Usually, a rise of 10 OC will double the rate of r...

Temperature For The Enzyme Amylase
2,232 wordsAn Investigation Into The Factors Affecting Then Investigation Into The Factors Affecting The Activity Of The Enzyme Amylase – Planning Hypothesis I predict that as the temperature increases, the speed of the reaction will increase. When a particular temperature is reached I believe the rate of reaction will dramatically decrease. I believe this because most chemical reaction happens faster when the temperature is higher. At higher temperatures molecules mover around faster, which makes it...

Green House Effect Gases
1,091 wordsGreenhouse gases (chlorofluorocarbons, carbon dioxide, methane, nitrous oxide, etc.) let heat in but stop it from going back out – like a windshield in a parked car. At our current rate of creating these gases by industry, cars and burning fossil fuels, scientists predict a temperature increase of 4 to 9 degrees F by 2050. (9 degrees F separates today's average temperatures from the last ice age.) The United Nations Panel on Climate Change recommends that we immediately cut our use of foss...
