For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in.
Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules.
Cracking is an example of a thermal decomposition reaction."

Is cracking of petroluem fraction a physical or chemical change?
Cracking of petroleum is a chemical process.
What is a process where molecules are split into smaller more useful molecules?
The process is called cracking. The best way of breaking them up uses heat and a catalyst, so we call this catalyst cracking.
What is the process of the breakdown of fats by repeated use and heating?
This is called Cracking.
What is the definition of haloclasty?
Is the process in which salt crystals form in cracks and expand causing cracking (weathering process)
What is the process in which large hydrocarbons are converted into smaller hydrocarbons which provide better fuel?
Process is called cracking.
Why is cracking an important process in oil refining?
Cracking is the most important process for the commercial production of gasoline and diesel
What are the advantages of thermal cracking over catalytic cracking?
Carbonium ion process
What are the advantages of catalytic cracking over thermal cracking?
Carbonium ion process
Is cracking of petroluem fraction a physical or chemical change?
Cracking of petroleum is a chemical process.
Why is aluminium oxide used whilst carrying out cracking reactions in a laboratory?
It lowers the activation energy of cracking, to quicken the cracking process.
Why is porous pot catalyst used in cracking hydrocarbons?
The 'porous pot' that is used in a lab, is used to facilitate the cracking process during heating, the porous pot is used as a catalyst to speed up the cracking process. This allows for the process to occur at a lower temperature.
What is the process that is used to refine petroleum called?
Cracking
What is the process that is used to refined petroleum called?
Cracking
What is the process that decomposes alkanes into alkenes?
This is usually called cracking; It produces unsaturated hydrocarbons as well as smaller alkanes.
How are petrochemicals broken down?
This chemical process is called cracking.
How can clarity be achieved?
The clarity of drinking water is achieved through the purification process.
What is a process where molecules are split into smaller more useful molecules?
The process is called cracking. The best way of breaking them up uses heat and a catalyst, so we call this catalyst cracking.
