Answers
Answer:
Those substances which can burn are called combustible substances. For Example: Cloth, straw, cooking gas, kerosene oil, coal, charcoal, wood, leaves, paper, wax, hydrogen gas, ethanol, methane, propane, propene. Flammable materials are combustible materials that ignite easily at ambient temperatures
Explanation:
please mark me brain list
Answer:
As we know that the combustible materials are those which can be easily ignited and burned. The combustible substances can be burned in the presence of air giving out heat and light. There are many substances which can be burned in the presence of air as it has presence of oxygen in it, which acts as a catalyst for the combustion. There are two types of combustion which take place in nature, complete combustion and incomplete combustion. In the complete combustion, the material is burned completely leaving no residue or carbon and incomplete combustion is the one where the substance leaves a residue after getting burnt.
Flammability is a degree applied to combustible substances to know how fast they can be burned. When it is written that a substance is highly flammable, it means that substance can easily catch fire at room temperature itself. Combustible substance which is a substance which burns in air and tends to produce heat and light is known as combustible substances. Those substances which can burn are called combustible substances. For Example: Cloth, straw, cooking gas, kerosene oil, coal, charcoal, wood, leaves, paper, wax, hydrogen gas, ethanol, methane, propane, propene. Flammable materials are combustible materials that ignite easily at ambient temperatures.
Note:
Remember that the combustible material is something that can burn in air. Flammable materials are combustible materials that ignite easily at ambient temperatures. The degree of flammability or combustibility in air depends largely upon the volatility of the material.
