They're both alkanes, and both gases at normal atmospheric pressures and standard temperatures. However, LPG is propane, and CNG is mainly methane; the two have different combustion characteristics, and can't be freely interchanged without making modifications to the hardware that uses them.

When cng or lpg undergoes complete combustion what products are formed?

When CNG or LPG undergo complete combustion, the products formed are carbon dioxide (CO2) and water (H2O). This process releases energy in the form of heat and light.

What is the differences between LPG and CNG?

CNG is basically composed of methane whereas LPG is a mixture of propane, butane and other chemicals.Another important difference from a physical point of view is thatCNG does not liquefy under high pressure - it remains a gas, unless it is cooled down to at least - 164°C. LPG on the other hand becomes liquid when it is compressed or when it is cooled down (therefore the name "Liquefied Petroleum Gas").CNG directly comes from a gas field. The only process, which sometimes needs to be done, is filtering the gas. But usually, the gas can be used as a fuel right away after the compression process. LPG, however, is an artificial product. It is a mixture of the above-mentioned gases. Hence, these gases need to be blended, before they can be used as fuel.CNG has a greater part of Hydrogen and is therefore lighter than air (this attribute in fact makes CNG very safe: once there is a leak in the system, the gas will simply be released to the atmosphere). LPG on the other hand, is twice as heavy as air. This gas is usually a by-product which accumulates from the oil drilling as well as the refinement of oil.in addition to what is above-another difference is simply their use. CNG is mostly used in vehicles while LPG is used for cooking in place of electric stoves.LPG is abbreviation of low pressure gas and CNG is compressed natural gasCNG mainly consists of Methane(CH4), whereas LPG mainly consists of Propane(C3H8) and Butane(C4O10)


What is the relationship between CNG density and its impact on fuel efficiency in vehicles?

The relationship between CNG density and its impact on fuel efficiency in vehicles is that higher CNG density typically leads to better fuel efficiency. This is because denser CNG contains more energy per volume, allowing vehicles to travel further on less fuel.


What is the optimal temperature for storing and using LPG gas?

The optimal temperature for storing and using LPG gas is between -44F and 120F.
