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.
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.
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.
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 elements are found in nuclear fuels?
Uranium, sometimes plutonium, oxygen
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
What processes increase carbon dioxide and oxygen in the atmosphere?
Processes that increase carbon dioxide in the atmosphere include burning fossil fuels, deforestation, and industrial activities. Photosynthesis by plants and algae is a key process that increases oxygen in the atmosphere.

What is oxygen bomb calorimeter?
An oxygen bomb calorimeter is a device used to measure the energy content of a sample by combusting it in a controlled environment and measuring the temperature change. The sample is sealed in a high-pressure vessel (the bomb) with oxygen, ignited, and the heat released is used to calculate the calorific value of the sample. This method is commonly used to determine the energy content of fuels and food.
What is calorific energy?
Calorific energy refers to the amount of heat energy released by burning a certain amount of fuel. It is commonly used to measure the energy content of fuels such as coal, oil, and natural gas. The higher the calorific value of a fuel, the more energy it can produce when burned.
What gas is needed to burn fuels?
Oxygen is needed to burn fuels as it is required for the combustion process to occur. When fuels are burned, they react with oxygen to produce heat and other byproducts.
Which element is required for the combustion of fossil fuels?
Oxygen is required for the combustion of fossil fuels. During combustion, the carbon and hydrogen in the fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
How oxygen is used to get energy?
By oxidizing fuels.
