How much CO2 does burning a gallon of gas emit?
19.64 pounds
About 19.64 pounds of carbon dioxide (CO2) are produced from burning a gallon of gasoline that does not contain ethanol.
How is 1 gallon of gasoline 19 pounds of carbon dioxide?
If each carbon atom in a gallon of gasoline becomes 3.6 times heavier when converted to carbon dioxide after combustion, then the 5.3 pounds of carbon in a gallon of gas becomes just over 19 pounds (8,650 grams) of carbon dioxide.
How much CO2 is produced per gallon?
Carbon Dioxide Emissions Coefficients
| Pounds CO2 | Kilograms CO2 | |
|---|---|---|
| Carbon Dioxide (CO2) Factors | Per Unit of Volume or Mass | Per Million Btu |
| Coal (All types) | 4,027.93/short ton | 95.74 |
| Natural Gas | 121.31/thousand cubic feet | 52.91 |
| Gasoline | 18.74/gallon | 70.66 |
How much CO2 is emitted when natural gas is burned?
Natural gas is a relatively clean burning fossil fuel About 117 pounds of CO2 are produced per million British thermal units (MMBtu) equivalent of natural gas compared with more than 200 pounds of CO2 per MMBtu of coal and more than 160 pounds per MMBtu of distillate fuel oil.
How does 1 gallon of gas become 20 lb of CO2?
When gasoline burns, the carbon and the hydrogen in the gas molecules separate. So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (. 87 x 6.3 pounds = 5.5 pounds). So, multiply the weight of the carbon times 3.7, which equals 20 pounds of carbon dioxide!
What does 20 gallons of gas weigh?
124 lbs is a good estimate.
Does gasoline produce water when burned?
So the burning of one gallon of gasoline produces 3,914.6 grams of water. This is equal to 8.6 pounds of water, which has a volume of 1.033 gallons. Thus the water vapor put into the atmosphere by burning gasoline is equal to 390 millions of gallons of water per day.
How many gallons of air does it take to burn a gallon of gas?
Since air is only 23\% oxygen by weight, it will take 113.5 pounds of air (26.1 ÷ 0.23) for the complete and perfect (0\% excess air) combustion of this gallon of fuel. Assuming there are 13 cubic feet of air to the pound, 1476 cubic feet of air are required to burn each gallon of fuel.
What is produced when you burn natural gas?
When natural gas is burned properly, by-products of combustion are primarily carbon dioxide and water vapor. Because methane contains only one carbon atom, natural gas produces less carbon dioxide than any other fossil fuel, and fewer other pollutants as well.
Does burning gas produce carbon dioxide?
The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
What is produced when you burn gas?
Gasoline contains carbon and hydrogen atoms. During combustion, the carbon (C) from the fuel combines with oxygen (O2) from the air to produce carbon dioxide (CO2). The additional weight comes from the oxygen.
What does one gallon of gas weigh?
6.1 pounds
According to the Science and Technology Desk Reference, a U.S. gallon of Gas weighs 6.1 pounds and an Imperial Gallon weighs 7.2 pounds.
How many pounds of carbon dioxide are in a gallon of gas?
So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (.87 x 6.3 pounds = 5.5 pounds). So, multiply the weight of the carbon times 3.7, which equals 20 pounds of carbon dioxide!
How much CO2 is produced when you burn gasoline?
Burning 6.3 pounds of gasoline produces 20 pounds of carbon dioxide. Huh!? Here’s how. Most of the weight of carbon dioxide (CO 2) comes from the two oxygen atoms (the O 2 ).
How much does a gallon of gasoline weigh?
Next, we need to know how much of the weight of the gasoline is just the carbon. Gasoline is about 87\% carbon and 13\% hydrogen by weight. So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (.87 x 6.3 pounds = 5.5 pounds). So, multiply the weight of the carbon times 3.7, which equals 20 pounds of carbon dioxide!
How much oxygen is used to burn 1 gallon of gas?
The total Oxygen taken from the atmosphere is 6.0 lbs (for H2O) + 13.9 lbs (for CO2) for a total of 19.9 lb of Oxygen used to burn one gallon of gasoline. How about seven years late? My question: the above describes the direct emission of CO2 for a gallon of gas.
