[amp_mcq option1=”sand and TNT” option2=”TNT and charcoal” option3=”nitre, sulphur and charcoal” option4=”sulphur, sand and charcoal” correct=”option3″]
The correct answer is C. Gunpowder consists of a mixture of nitre, sulphur and charcoal.
Nitre, also known as saltpeter, is a mineral that is found in the earth. It is a compound of potassium nitrate, which is a strong oxidizer. Sulphur is a non-metallic element that is found in nature. It is a yellow, odorless, and tasteless solid. Charcoal is a black, solid form of carbon that is made by heating wood or other organic materials in the absence of air.
When these three ingredients are mixed together, they form a powerful explosive. Gunpowder is used in a variety of applications, including firearms, fireworks, and explosives.
Option A is incorrect because sand is not a component of gunpowder. Sand is a granular material that is made up of small pieces of rock. It is used in a variety of applications, including construction, landscaping, and glassmaking.
Option B is incorrect because TNT is not a component of gunpowder. TNT is a high explosive that is made up of trinitrotoluene. It is used in a variety of applications, including mining, construction, and demolition.
Option D is incorrect because sulphur, sand, and charcoal are not the only components of gunpowder. Gunpowder also contains potassium nitrate, which is a strong oxidizer.
