No. Oxygen is not a fuel, so it has no calorific value. Some people confuse "combustion" (burning a fuel) with "supports combustion" (allows burning to take place). Oxygen supports combustion, but does not burn itself. Therefore it has no calorific value.

Why charcoal burns slowly when left undisturbed?
Because when you blow on the coals you are adding oxygen to the fire and oxygen fuels a fire. A fire would simply go out without any oxygen. Because when you blow on the coals you are adding oxygen to the fire and oxygen fuels a fire. A fire would simply go out without any oxygen.
Advantages of fuels?
Advantages of fuels: Easily Available, Produce Large Amount of Energy, High Calorific Value and Stability. The highest consumption rate in todayâ??s world is of fossil fuel.
What do you mean by calorific value of fuels and how can you determine the colorific value of solid liquid and gas?
calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt. from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.
Why is fuel needed for a fire?
We burn the following fuels: * Biofuels: wood, bagasse, biodiesel (other liquid biofuels), alcohol, cow dung * Fossil Fuels: Coal, oil products, natural gas, peat * Processed fuels: Methane, ethane, butane * Recycled fuels: Scrap wood, paper, plastic, waste gases like CO
What are the main troubles with fossil fuels?
One of the problems with fossil fuels is that they pollute the environment by adding greenhouse gases to the atmosphere, thereby causing global warming.
Explain that different fuels have different calorific value and the consequences of this?
Different fuels have different calorific values means that the different fuels have different energy contents. The consequence of this is that for a given energy output, more fuel is required with the liower calorific fuel.

Why is net calorific value is less than gross calorific value?
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered.sayed karar waris
What are bio-fuels used for?
biofuels make energy from living things or their waste products

Can oxygen be a fuel?
No, but most fuels need oxygen to burn.

How oxygen is used to get energy?
By oxidizing fuels.
What Fuels are chemicals which can burned to give?
oxygen
Is oxygen present in fossil fuel?
Turn out that it is not present (OXYGEN in fossil fuels).
What do hydrocarbon reacts with when fossil fuels are burned?
Oxygen
What chemicals are inside fuels?
Most fuels consist of various combinations of the elements carbon, hydrogen, and oxygen.
