Question

Prepare a list of combustible and non combustible substances.

Answer 1

Hint :Combustion is a high-temperature exothermic redox chemical process that creates oxidised, generally gaseous compounds in a mixture known as smoke. Because a flame is only visible when components undergoing combustion vaporize, combustion does not always result in fire, but when it does, a flame is a typical sign of the process.

Complete Step By Step Answer:
Combustibility refers to how quickly a material may burst into flame when exposed to fire or combustion. When a substance is utilised for building or storage, this is a key feature to consider. It's also crucial in procedures that result in flammable compounds as a by-product. For compounds that are easily flammable, further precautions are frequently necessary. Installation of fire sprinklers or storage away from potential sources of ignition are examples of these procedures. Low-flammability materials may be used in construction where the danger of fire must be minimised, such as apartment buildings, residences, or workplaces.
Fuel oil, paint, kerosene, paints, cesium, magnesium, aluminium powder, calcium, sawdust, plastic dust, coal, flour, and powdered metal are all flammable materials. The difference between flammable and combustible liquids is that flammable liquids have flash points below 100 degrees Fahrenheit, and combustible liquids have flash points over 100 degrees Fahrenheit. The lowest temperature at which a liquid emits enough vapour to start burning is known as the flash point.
A non-combustible substance is one that does not ignite, burn, or sustain combustion.
When exposed to fire or heat in the form in which it is used and at the conditions expected, it does not emit flammable fumes.
Portland cement concrete, gypsum concrete, and magnesite are examples of non-combustible materials. Portland cement stucco, Portland cement plaster, and gypsum plaster are among the items in this category, as are concrete, brick masonry, concrete block masonry, and ceramic tiles. Magnesium and magnesium alloys, with the exception of aluminium (which is categorised as restricted - combustible). Here you'll find sheet glass, block glass, and uncoated glass fibres.

Note :
Combustible substances: Combustible substances are those that burn or undergo combustion. Paper, fabric, cooking gas (LPG), compressed natural gas (CNG), kerosene oil, wood, charcoal, and so on.Combustible substances are those that do not burn. Non-combustible substances are those that do not burn.Stone, cement, bricks, dirt, sand, water, iron nails, and so on.
