Arrange the following fuels in the increasing order of their calorific...
To arrange the fuels in increasing order of calorific value:
1. Hydrogen gas: Hydrogen has the highest calorific value among the listed fuels, around 141.8 MJ/kg (MegaJoules per kilogram).2. Kerosene oil: Kerosene oil has a high calorific value, ranging from 42.5 to 46.2 MJ/kg.3. Charcoal: Charcoal has a moderate calorific value, typically around 33 MJ/kg.4. Wood: Wood has the lowest calorific value on this list, with an average of around 15 MJ/kg (depending on the wood type and moisture content).
- Correct Order: 4. Wood, 3. Charcoal, 2. Kerosene oil, 1. Hydrogen gas
- Explanation:
- Wood: Lower calorific value due to higher moisture content.
- Charcoal: More calorific value than wood due to lower moisture content.
- Kerosene oil: Higher calorific value compared to charcoal.
- Hydrogen gas: Highest calorific value due to complete combustion producing only water vapor.
- Correct Answer: D: 4, 3, 2, 1
- Correct Order: 4. Wood, 3. Charcoal, 2. Kerosene oil, 1. Hydrogen gas
- Explanation:
- Wood: Lower calorific value due to higher moisture content.
- Charcoal: More calorific value than wood due to lower moisture content.
- Kerosene oil: Higher calorific value compared to charcoal.

Arrange the following fuels in the increasing order of their calorific...
The calorific value of a fuel is the amount of energy released when it is burned completely. The fuels given in the question can be arranged in the increasing order of their calorific value as follows:
1. Wood - Wood has the lowest calorific value among the fuels given in the question. This is because wood is mostly made up of cellulose, hemicellulose, and lignin, which are complex organic compounds that do not burn completely. As a result, wood releases less energy when it is burned compared to other fuels.
2. Natural gas - Natural gas has a higher calorific value compared to wood because it is mostly made up of methane, which is a simple hydrocarbon that burns completely. When natural gas is burned, it releases a large amount of energy in the form of heat.
3. Petrol - Petrol has a higher calorific value compared to natural gas because it is a more complex hydrocarbon that contains more carbon and hydrogen atoms per molecule. When petrol is burned, it releases a large amount of energy in the form of heat and light.
4. Coal - Coal has the highest calorific value among the fuels given in the question. This is because coal is mostly made up of carbon, which burns completely to release a large amount of energy. Coal also contains other elements like hydrogen, sulfur, and nitrogen, which contribute to its calorific value.
Therefore, the correct order of increasing calorific value of the fuels given in the question is (ii), (iii), (i), and (iv), which is option D.
1. Wood - Wood has the lowest calorific value among the fuels given in the question. This is because wood is mostly made up of cellulose, hemicellulose, and lignin, which are complex organic compounds that do not burn completely. As a result, wood releases less energy when it is burned compared to other fuels.

Coal also contains other elements like hydrogen, sulfur, and nitrogen, which contribute to its calorific value.
