Advantages and Disadvantages of Petrol

Petrol is a transparent liquid which is derived from petroleum and it used as a fuel in internal combustion engines. The main constituents of petrol are organic compounds which are obtained by the process of fractional distillation of petroleum.

Advantages of Petrol:
  • Though there is rapid rise in cost of petroleum, it is still cheaper than any other fuel.
  • Petrol has higher density than any other energy form of energy.
  • It is relatively safe of store, carry and dispense.
  • Petrol is obtained from distillation process which is not difficult to make.
  • The process of production of petrol does not need rare materials and the process does not involve letting out byproducts that are dangerous to the environment.
  • Petrol makes an excellent source of organic molecules which can be used for building plastics, fiber, medicines, etc.
  • Petrol can withstand high heats without breakdown and it makes useful lubricants like engine oil and grease.
  • The residues of petrol make good surface for pavement roads and also as waterproof materials for roof.
  • Certain petrol components make brilliant solvents for paint, industrial uses etc.
  • Other components of petrol like the propane and butane make very good compact source of portable cooking fuel and heating.
  • Natural gas obtained is used to make fertilizers which are used in agriculture and household detergents.
Disadvantages of Petrol:
  • Supply of is decreasing and one will petrol supplies will be exhausted.
  • There is a high demand of petrol.
  • Price of petrol is increasing everyday.
  • Burning of petrol affects the environment as it produces carbon.
  • Petrol is a carbon based fuel and burning of this fuel increases the production of CO2 which is a greenhouse gas and is said to cause global warming.
  • There are many wars fought over oil and it is having a negative influence on relations between nations.
  • Transport of petrol is dangerous.
  • Oil spills during extraction of crude oil or transportation have catastrophic effects on the affected areas.
  • Crude oil producing areas are at chances of having severe weather conditions.
  • Petrol contains some cancer causing compounds like benzene.
  • The volatile components of petrol cause smog.

Question:Can you guys please give me some advantages and disadvantages of petrol? It's for science on Monday. Thanks :D

Answers:Its not sustainable when its gone its gone, it causes pollution when its burned off, it causes a lot of fighting in the world and the price is never steady it always changes and we are at the mercy of price increases and decreases. But its easy to use because its in high demand, its better for your vehicles than ethanol (ethanol burns hotter and melts parts in peoples cars, my dad sees costly damages where he works from people who thought the money saved buying ethanol or a blend of ethanol and gasoline was a good idea.) Ethanol also creates extra pollution because it takes power to make. Where oil takes less. Also right now its currently cheaper to produce than ethanol but ethanol gets government grants and stuff so they can encourage people to buy it because its cheaper.

Question:were doing a speech if you could ban a piece of modern technolgy what would it be and why I chose petrol i need some ideas please

Answers:Advantages: It's relatively concentrated, you can carry enough in a car to take you hundreds of miles. At the time we made the decision to rely on it as a motor fuel it was cheap and plentiful. Despite its explosiveness and flammability it's relatively easy and safe to store, dispense, carry around in cars. It's not very difficult to make, just distillation of petroleum that comes from the ground, I mean it is processed without needing scarce materials or environmentally dangerous processes or dangerous waste products. Disadvantages: The natural supply of crude oil continues to grow more and more scarce, which naturally raises the price progressively. Every barrel we pull out of the ground makes the remaining supply more valuable so not only do prices go up but there will be wars and imperialism in attempts to gain control of the supply, and this will go on continuously, with increasing intensity, until it is gone! Fossil fuels release billions of tons of carbon into the atmosphere, causing serious global climate change that endangers our lifestyle, perhaps our lives themselves. We are burning up the world's supply of petroleum, a cheap, easy to process material that has many other uses--making materials (like plastics), chemicals, pesticides, fertilizers, etc. The cheap price of petrol (cheap relative to actual cost) encourages us to use it in wasteful ways, commuting and traveling alone in cars for instance. But if you're going to ban it (or more reasonably, to pass laws severely restricting the way we use it, you need to come up with a good alternative strategy. Encouraging public transportation, hydrogen, biofuels, hybrids, or some combination of things like this.

Question:' We are planning to buy vehical/s for line sales.We shall be carring about 200 Kgs.articals(light weight) plus the weight of driver and a sales man. In all, the load on vehical will not be more than 300/325 Kgs.The vehical will be running around 200 t0 250 k/m in ren hours.This is being the situation which vehical would be more priferable / economical and viable for us.Whether we should go for petrol operated or gas operated one.What are the advantages and dis advantages in both versons, and whether gas operated vehical's engine will have more repairing cost after use of about an year? '

Answers:The only good thing about LPG is that it can never go more then half of what petrol's worth and that's about it. Petrol has more power, torque, it doesn't drink as much as gas and they generally more reliable. If your carrying lots of weight get the petrol. Gas is only really good for taxi's or people who drive 6 cylinders. Good Luck

Question:why most industrial engines are diesel? is there any kind of diesel engines with dimensions less than petrol? why petrol engines are not as expensive as diesel ones

Answers:Advantages: Diesel fuel is denser. Since the price per liter is generally less than petrol, the price per joule of energy is also less. Diesel engines use a higher compression ratio. That makes them more efficient. Diesel engines are also more efficient when running unloaded. Higher efficiency means lower Carbon dioxide emission per distance traveled and weight hauled. Diesel engines run in a lower speed range and produce more torque at lower speed making it easier to start heavy loads. Diesel engines are generally built to last longer. Disadvantages: Diesel engines are heavier because of the higher compression and because they run slower and therefore need more torque and piston displacement to produce the same power. Diesel engines are noisier. They produce more soot emissions and burn fuel containing more sulfur, but this is currently being improved. Diesel engines are more expensive because of the compression ratio and the size and weight.
