Permeable Membrane Semi Permeable
781 wordsOsmosis is the flow of water through a semi permeable membrane that blocks the transport of salts or other solutes through it. It is also defined as the net movement of water from an area of high concentration to a region of low concentration. Osmosis is a fundamental effect in all biological systems. When two water volumes are separated by a semi permeable membrane water will flow from the side of low solute concentration to the side of high solute concentration. If external pressure is applied...

Carbon Dioxide Measuring Cylinder
3,019 wordsAim 1 To find Fermentation Aims Aim 1 To find out what factors affect how quickly bread dough rises. There are a number of factors that affect how quickly bread dough rises. These are: · Amount of sugar-if the amount of sugar is increased, the rate of reaction will increase. Adding a higher concentration of sugar will increase the sugar particles in a given space. As the mixture is heated, the sugar particles will begin to move. Due to a lack of space, this would result in collisions. Thu...

Methane Nitrous Oxide Carbon Dioxide Emissions
1,396 wordsGlobal Warming The Greenhouse Effect The greenhouse effect is a term that is used to refer to an atmospheric process. The greenhouse effect is the inability of long wave radiation to escape the atmosphere causing increased air temperature and increasing impurities in the atmosphere. During the last 20 years the media and public have given the topic priority consideration. There is some evidence that the atmosphere is warming and strong indications that the greenhouse effect is responsible. It is...

Burning Fossil Fuels Natural Greenhouse Effect
3,312 wordsThe Greenhouse Effect The greenhouse effect, as defined in the dictionary, is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earths atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. Even though this process occurs naturally and has kept the Earths temperature about 60 degrees Fahrenheit warmer than it would otherwise be, current life on Earth could not be sustained with...

Rate Of Reaction Calcium Carbonate
2,367 wordsInvestigation Into The Relationship Between Temperature Of Investigation Into The Relationship Between Temperature Of Acid And The Rate Of Reaction In The Reaction Of Caco 3 And Hcl Background Information The speed at which reactants are converted into products during a reaction is referred to as its rate. Usually in a reaction, the amount of the product of the reaction is measured to work out the rate of the reaction. In this reaction, the rate will be calculated by the equation: Rate = 1 Time....
