A type of wax called cutin is produced by the epidermal cells of plants, forming a water-resistant coating on the surfaces of stems, leaves, and fruits. This helps the apple conserve water and also acts as a barrier to infection.
Other than this natural cutin , there is artificial waxing done on apples for preserving. This artificial waxing is legal in US with restrictions on the type of wax used and the thickness etc.
As usual, there is illegal waxing also done on apple as an adulteration method.
What else can I help you with?
It could be shiny or pearly?
When an object appears to be shiny or pearly, it typically means that it has a smooth and reflective surface that is capable of reflecting light. This can create a lustrous or iridescent appearance, giving it a shiny or pearly quality depending on the material and light conditions.
What is shiny luster?
Shiny luster is a term used to describe the appearance of a mineral or metal surface that reflects light and appears glossy or reflective. Minerals with a shiny luster include metals like gold and copper, as well as some non-metallic minerals like pyrite and graphite. This luster is caused by the arrangement of atoms on the surface of the material, which allows light to be reflected in a specific way.
Is glass shiny or dull?
Most glass is shiny but can be made to look dull.
What is the term for how shiny or dull an object appears?
The term you're looking for is "luster." It refers to how light reflects off the surface of an object, giving it a shiny or dull appearance.
What is irons luster?
The luster of iron is metallic, meaning it has a shiny, reflective surface. This is due to its ability to reflect light evenly off its surface.
Why do shiny surface do not absorb light?
Shiny surfaces do not absorb light because they have a smooth surface that reflects most of the light that hits them. This reflection prevents the light from being absorbed into the material, giving it a shiny appearance.
Why do you use sandpaper on substances to make them shiny?
To make a surface shiny, the surface irregularities must be minimized. Sandpaper helps in leveling surface irregularities. Polishing any material that can be polished is one way of making it more attractive.
Is brittle shiny or dull?
Brittle materials can exhibit both shiny and dull appearances. Whether a brittle material looks shiny or dull depends on its composition and surface characteristics. Some brittle materials might have a shiny appearance due to a smooth surface finish, while others may appear dull if they have a rough or textured surface.
What the property of matter meaning shiny?
The property of matter that makes it shiny is called luster. Luster refers to the way light interacts with the surface of a material, causing it to reflect light in a way that appears shiny or metallic. Materials with high luster, like metals, have a smooth surface that reflects light well, giving them a shiny appearance.
Would you expect a dull or shiny surface to be a better absorber?
A dull surface would be a better absorber of light because its rough texture allows for greater light absorption due to increased surface area and multiple reflections within the material. Shiny surfaces reflect more light and are therefore poorer absorbers.
What is the use of the inspection of the fracture surface to determine the percentagr of the shiny surface?
The inspection of the fracture surface is commonly used in materials science to assess the ductility and toughness of a material. The percentage of shiny surface, also known as the "percent shear area," can provide valuable information about the mode of fracture (e.g., ductile or brittle) and the energy absorbed during fracture. A higher percentage of shiny surface typically indicates a more ductile fracture, while a lower percentage suggests a more brittle fracture. This analysis is crucial for understanding the mechanical properties and failure mechanisms of materials.
Do mercury shiny?
Fresh mercury surface is shiny.
Why is there a shiny surface at the back of the radiator?
The shiny surface is a reflector, to reflect the heat outwards towards you.
It could be shiny or pearly?
When an object appears to be shiny or pearly, it typically means that it has a smooth and reflective surface that is capable of reflecting light. This can create a lustrous or iridescent appearance, giving it a shiny or pearly quality depending on the material and light conditions.
Do a black surface cool faster than shiny surface?
No, a black surface will absorb more heat from its surroundings and radiate it back out more slowly compared to a shiny surface. This means that a shiny surface will typically cool faster than a black surface.
What surface emits more radiation white shiny or silver shiny?
silver shiny
Is Zr a shiny solid?
A fresh surface of zirconium is shiny.
