Particles are arranged in no particular order in this type of solid?
amorphous
Define amorphous solid?
Generally they are two types of solids 1. Crystalline solids 2. Amorphous solids. Amorphous solids are those solids which having different properties in different directions. They didnt have sharp melting and boiling points.
What are these type solid Tar candle wax and glass?
Amorphous solids
List in increasing order of melting temperature HDPE PMMA LDPE?
In increasing order, LDPE has the lowest melting point at 221 to 239 degrees Fahrenheit. It is followed by HDPE at 266 degrees Fahrenheit and PPMA at 320 degrees Fahrenheit.
What properties do liquid and gases have due to the movement of their molecules?
Liquids and gases are amorphous (shapeless), viscous (can flow), and diffuse (have internal space) due to the movement of their molecules.
List in increasing order of toughness HDPE PMMA LDPE?
PMMA LDPE HDPE
Is PMMA natural or synthetic?
PMMA is a synthetic material, made through a polymerization process of methyl methacrylate monomers. It is not naturally occurring in nature.

When substances are formed and the particles lack order they are called?
Amorphous.
Is polyurethane amorphous or crystalline?

What glue is needed for PMMA?
Your typical cyanoacrylaye or SuperGlue.
What element are found acrylic paint?
Acrylic, or poly (methyl methacrylate) (PMMA) is a compound made op from carbon, oxygen and hydrogen. Acrylic paint is not a compound but an suspension of PMMA in water. However, PMMA is hydrophobic and so other compounds need to be added to enable the suspension to form.
Why PMMA is transparent?
PMMA (polymethyl methacrylate) is transparent because its molecular structure allows light to pass through easily without significant scattering or absorption. The repeating methyl methacrylate units in PMMA align in a regular pattern, which helps minimize light distortion and enhances transparency.
