Question

pls answer in your own words some explainable , short , sweet ....
1. Explain combustion
2. What is ignition temperature
3. What is inflammable substances​

Answer 1

1)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.

2The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.

3Inflammable substances : Substances which have very low ignition temperature and can catch fire easily are called inflammable substances. For example: petrol, alcohol, LPG (liquefied petroleum gas), CNG (Compressed natural gas) etc.

thank u so much my dear frndz......

Answer 2

$\huge{{\mathfrak{Questions :-}}}$

1.Explain combustion

2. What is ignition temperature

3. What is inflammable substances

$\huge\pink{\underline{Answer :-}}$

• Combustion is a process which can burn something .It is a chemical reaction between Fuel and Oxygen .

➜ Formula of combustion is :-

➜ Combustion reaction is Hydrobcarbon + Oxygen = Heat energy.

• It means that a substance is the lowest temperature at which it spontaneously ignites in normal atmosphere without an external source of ignition. EXAMPLE : Candle flame & Fire.

• An inflammable substance or material burns very easily: a highly inflammable liquid example is petrol.
