What do you mean by combustion?

Question

Answer

Combustion is a chemical reaction  that is the process  of burning and produce oxygen

Answer

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat.

Answer

A Chemical process in which a substance reacts with oxygen to give off heat is called combustion.

Answer

What is Combustion?
Combustion is a chemical reaction that occurs when a fuel combines with an oxidant, typically oxygen, producing heat and light. This exothermic reaction is fundamental to various processes, including energy production, cooking, and propulsion.
Types of Combustion
- Complete Combustion:
- Occurs when there is sufficient oxygen.
- Produces carbon dioxide (CO2) and water (H2O).
- Example: Burning of propane in a gas stove.
- Incomplete Combustion:
- Occurs when oxygen supply is limited.
- Produces carbon monoxide (CO), soot, or other hydrocarbons.
- Example: Burning wood in a fireplace.
Stages of Combustion
- Ignition:
- The initial energy input needed to start the reaction.
- Can be provided by a spark, flame, or heat.
- Propagation:
- The reaction continues as long as fuel and oxidant are available.
- Heat generated can sustain the reaction.
- Extinction:
- The process ends when fuel or oxygen is depleted.
- Can also occur if the temperature falls below the ignition point.
Applications of Combustion
- Power Generation:
- Used in thermal power plants to produce electricity.
- Transportation:
- Fuels like gasoline and diesel power vehicles.
- Industrial Processes:
- Essential in manufacturing and processing materials.
Environmental Impact
- Air Pollution:
- Incomplete combustion can release harmful pollutants.
- Greenhouse Gases:
- CO2 emissions contribute to climate change.
Understanding combustion is crucial for improving efficiency and reducing environmental impacts in various applications.

Answer

Burning of a substance in oxygen to produce heat and light is called combustion

Answer

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion in a fire produces a flame, and the heat produced can make combustion self-sustaining.
