Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Earth Surface Rise In Sea Level
802 wordsGlobal Warming Global Warming, aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 steps in the Greenhouse effect. 1 -Sunlight radiates from the sun, through space, to earth? s atmosphere. 2 - the sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3 - Infrared rays, which are remitted i...

Surface Of The Earth Nitrous Oxide
613 wordsGlobal Global Warming Introduction: Global warming is a term that describes the green house effect-that is rise in temperature of the earth. The earths climate is predicted to change because activities are altering the chemical composition of through the building up of green house gases-primarily CO 2, CH 3, N 2 O and chlorofluorocarbon. These green house gases trap energy from the sun and heat would not escape back in to space. Thus, they warm our world. But problem is arising because the atmos...

Greenhouse Gases Infrared Radiation
431 wordsGreenhouse Effect Greenhouse Effect, term for the role the atmosphere plays in insulating and warming the earths surface. The atmosphere is pretty much transparent to incoming solar radiation. When this radiation strikes the earths surface, some of it is absorbed, warming the earths surface. Earth s surface emits some of this energy back out in the form of infrared radiation. As this infrared radiation travels through the atmosphere, most of it is absorbed by atmospheric gases like carbon dioxid...
