Find out why is CNG is preferred as a girl over diesel. Prepare a report on the advantages and disadvantages of CNG as an automobile fuel

Here's what I find  

Explanation:

1. Advantages

(a) Less atmospheric pollution

Low emissions — less CO, CO₂, HC, and NOₓ.

(b) Less noise pollution

CNG engines are quieter than gasoline and diesel

(c) Economic

(i) Lower maintenance costs

(ii) Cheaper fuel than gasoline and diesel.

(d) Safer

CNG cylinders are less dangerous than gasoline and diesel tanks in case of an accident.

(e) Lower maintenance costs

Longer periods between tune-ups and oil changes.

(f) Better performance

An octane rating of approximately 120. Regular gasoline is about 87 octane.  

2. Disadvantages

(a) Higher up-front cost

CNG vehicles are more expensive than the diesel/gasoline versions.  

(b) Shorter range

Shorter range means more frequent fill-ups.

(c) Limited Accessibility

(i) Few makers are building CNG automobiles

(ii) Relatively few CNG fuel stations

(d) Poorer performance

The added weight of the fuel tank reduces acceleration and performance.

(e) Reduced storage space

Bulky fuel tanks reduce cargo space.  

(f) Safety

Gaseous methane requires better engineering to prevent leaks.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.
