Why is there a danger of explosions in places such as silos and coal mines where there are large quantities of powdered combustible materials?
- because the large quantities of the powdered and combustible materials incluse two factors of increasing the reaction rate, which are more surface areas and high concentration.
- And also in such these places the tempreture is high more often, so it will lead to more collision between particles and speeding up the reaction rate as well.
- And the final reaction will be as an exothermic, so the energy will be released in the form of eplosion and flames.

Difference between gypsum bonded and phosphate bonded investment materials?
gypsum bonded materials are available in powder and liquids form. they consist of mixtures of silica and calcium sulphate hemihydrate [gypsum product] and some minor components such as powdered graphite and powdered copper and some modifiers to control setting time. silica bonded materials are composed of powered quartz and cristobelite and silica gel, magnesium oxide for maintaining pH. on heating silica gel converts into silica.
What do you get when powdered quartz and powdered limestone are soda are mixed?
When powdered quartz, powdered limestone, and soda (sodium carbonate) are mixed together, it forms a type of glass known as soda-lime-silica glass. This type of glass is commonly used in windows, bottles, and containers due to its durability and transparency.
Is iron filings and powdered sulfur a homogeneous mixture?
No, iron filings and powdered sulfur are a heterogeneous mixture because they do not mix uniformly. You can see distinct particles of both substances when they are mixed together.
What is powdered limestone?
Powdered limestone is a finely ground form of limestone rock. It is commonly used in agriculture, construction, and other industries as a soil amendment, building material, and as a component in various products such as paints and adhesives.
The streak test that is used to identify minerals involves studying the -?
The streak test involves studying the color of the powdered form of a mineral. This is typically done by rubbing the mineral against an unglazed porcelain tile to see the color of the streak left behind. This test can help identify minerals with different colors in their powdered form compared to their natural form.
What are the differences between combustible and non combustible dust?
Combustible Dusts have a KST value of Greater Than Zero, and can cause a Week to Very Strong Explosion... (Powdered Milk, Sugar, Coal, Wood, Plastic, Food/organic, Aluminum, Zirconium). Non-Combustible Dust, have a KST Value of Zero, and Don't cause an Explosion: Non-Combustible Dusts: Aggregates, such as stone, silica(sand), Silicates, Sulfates, Nitrates, Carbonates, Phosphates, Portland cement, Sand, Limestone.
What is combined powdered?
You think probable to amixture of powdered materials.
Why does bottles of powdered metals reads explosion possible?
Many common powders made in industry are combustible; particularly metals or organic materials such as flour. Since powders have a very high surface area, they can combust with explosive force once ignited. Facilities such as flour mills can be vulnerable to such explosions without proper dust mitigation efforts. Some metals become especially dangerous in powdered form, notably titanium.
Why it is more difficult to burn some combustible substances than others?
There are many variables which affect the ease of combustion. The degree of mixing with the air is a very large factor. Powdered coal dust in air will ignite explosively, while lumps of coal are much harder to ignite. Different compounds have different activation energies for combustion and there require different temperatures to ignite. Sometimes combustible materials are mixed with non-combustible materials which also makes them harder to burn; for example, dry paper burns quite well, but wet paper is very difficult to burn.
Is rainwater a heterogeneous or a homogeneous?
If the rain water contain powdered materials the mixture is nonhomogeneous.
Is clove combustible material?
Yes, clove is considered a combustible material. Being an organic substance, it can catch fire and burn when exposed to an open flame or high heat. Additionally, in its powdered form, clove can be more easily ignited due to its increased surface area. Proper storage and handling are essential to prevent accidental ignition.
What are the natural origins of the materials used in pencil?
The lead in a pencil is mostly a mixture of powdered graphite and clay.
What is the function of a ladle in laboratory?
A ladle is used in laboratry to transfer small amounts af powdered or granular materials.
What kind of physical filter are used?
Filters from paper, ceramics, glass, textiles, plastics, powdered or granulated materials, active carbon, etc.
How much sugar do you need to make chocolate?
1 box powdered coca 1 box powdered sugar so equal quantities of both.
How do you make sulphur candle?
To make a sulfur candle, you would typically mix powdered sulfur with a binding agent such as clay or other combustible material. The mixture is then molded into candle shapes and allowed to dry. When lit, the candle releases sulfur fumes used for fumigation purposes.
What did the framers wear?
powdered wig
