Save>> Petrol; Cure>> Acid Rain!!



GG < Save petrol to cure acid rain?? How???

CC < Geez.. Dont use car!

GG < Then i cant go to work!

CC < Use public transport then.

GG < I dont like public transport! I hate to walk all the way to the bus station and throw away my lovely 30 minutes for a god damn bus to arrive...

CC < Be grateful that ur saving the environment! Acid Rain is baad for us. Burning of petrol will only emit more carbon and sulphur particles to the atmosphere. Sulphur particles like sulphur dioxide and sulphur trioxide are sources of Acid Rain!

GG < You freaky lil Mother Nature lover...What is exactly we are trying to archieve here..

CC < We are trying to save Mother Nature! Do you know that avoiding high speeds on open roads results in safer driving and better fuel economy. In highway driving, more than 50% of the power produced by the engine is used to overcome aerodynamic drag. and thus fuel consumption increases rapidly at speeds above 90km/h.

GG < Uh Huh..

CC < On the average, a car uses about 15% more fuel at 100km/h, and 25% more fuel at 110km/h compared to when it is doing only 90km/h. However, this does not conclude that the lower the speed, the better the fuel economy - because it is not. The petrol consumption of an average car will increases sharply at speeds below 50km/h. So, it is best to drive in between 60-90 km/h.

GG < Oh Com' on... I was late for my meeting back then...

CC > Serves you right. And i bet you always idle your car while waiting for DD to get dressed up for your date.

GG > No.. Sometimes i parked my car around the corner..

CC < Oh reaally... If you are going to be idling for more than 5 minutes, you should switch off your engine. Idling more than a minute consumes much more fuel than restarting the engine. By having it switched off, you will save more petrol than is lost from the burst of petrol in restarting the engine.

GG < Oooo.. Wow... Thats amazing.. I feel enlighten...

CC < U should be.. Moreover, anticipation of traffic condition ahead can reduce petrol consumption up to 10% by adjusting the speed accordingly. It take up as much as 6 times more petrol to move a car from a dead stop than it does for one moving at just a few km/h. And i know you would tailgate every single car just to reach your destination on time.

GG < Im trying to tailgate the car so that other people wont cut in my lane.

CC < Letting them cutting into your lane wont hurt..

GG < It does..

CC < No it wont.. Another last reminder on how to save petrol. Remember to inflate your tires properly, check your tire pressures at least once a week. Research by the RAC Foundation shows that 20% under inflation (typically 6psi) can increase your fuel consumption by 3%, reducing tires life by 30% . So deal with it. Save petrol. Cure Acid Rain.

GG < Sigh.. Alright...

EFFECTS OF ACID RAIN

  1. Acid rain can increase the acidity of lakes, dams and streams and cause the death of aquatic life.
  2. Acid rain can increase the acidity of soil, water and shallow groundwater.
  3. Acid rain has been linked with the death of trees in Europe and North America. In spite of a great deal of research, no one yet knows exactly how acid rain harms forests. Most of the forests of Europe consist of huge areas of one tree species. This encourages the spread of plant pests and diseases. It seems likely that acid rain weakens the trees, perhaps helped by other pollutants such as ozone, and then leaves the trees open to attack by disease. Acid rain also disrupts the availability of soil nutrients. The final death of a tree may result from a combination of stresses such as heat, cold, drought, nutrient disruption and disease. It seems that the slow-growing, longer lived forests of the North may be more susceptible than the faster growing, shorter lived forests of South Africa.
  4. Acid rain erodes buildings and monuments. Acid particles in the air are suspected of contributing to respiratory problems in people.

What is Acid Rain



Ahhem hem hem... Basically, the word ACID RAIN is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. It has harmful effects on plants, aquatic animals, and infrastructure. primarily emissions of Sulfur dioxide (SO2) and nitrogen oxides (NO) resulting from fossil fuel combustion.


In fact, distilled water which contains no carbon dioxide, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are bases. “Clean” or unpolluted rain has a slightly acidic pH of about 5.2, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid (pH 5.6 in distilled water), but unpolluted rain also contains other chemicals. Below is an exquation of formation of acid rain.
