In its "raw" state, it contains a lot of impurities, even water. All that has to be gotten rid of, if the gas shall burn consistently and reliably.
it is fossil fuel go aqw
Renewable resources can still be used up before they can be renewed.
No... while metals are recyclable, they do not decompose like vegetation. They need to be processed and refined.
You need oxygen, heat, and fuel.
Bacteria need energy to fuel cellular activities.
yes it needs to be processed before it is used
no
Natural gas.
Fuel is material which is processed (usually 'burnt') to produce energy - heat or power. To move a car takes energy - and that has to be supplied by the fuel.
Both cooking oils (vegetable oils) and lards, fats, suet (animal fats) are man made as they need to be processed before being used in cooking.

No.
natural foods come straight from the ground basically and have lots of vitamins and minerals and stuff needed for survival while processed foods lose a lot of the stuff we need for survival and have a lot of added chemicals. edited by: Josiah Siddle :)
Prunes are dried plums. They are cleaned and processed before drying. They don't normally need to be cleaned.

Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
If you have a warning light telling you there is water in the fuel, you will need to park the car immediately. You will then need to drain all of the fuel from the car before putting more gas in.
