Polyethylene is a high melting solid because its molecular structure consists of long chains of repeating ethylene units, which allows for strong intermolecular forces to hold the chains together. These strong forces require a high amount of energy to break, resulting in a high melting point for polyethylene.

What is the melting point of polyethylene glycol 6000?
The melting point of polyethylene glycol 6000 is approximately 50-52°C.
What materials have a high melting index?
Materials with a high melting index typically include metals such as tungsten, molybdenum, and tantalum, which have high melting points and are often used in high-temperature applications. Other materials like certain polymers, such as high-density polyethylene (HDPE) and polypropylene, also exhibit high melting indices, indicating they can flow easily when heated. Additionally, ceramics and certain composites can have high melting indices, making them suitable for extreme thermal environments.
What solid is very hard and has a very high melting point?
Tin
What is the physical change of a solid at the melting point?
It turns from a solid to a liquid
What is the melting temperature of polythene bag?
Low-density polyethylene (LDPE), used for plastic storage bags, melts at about 110 degrees Celsius. High-density polyethylene (HDPE), used for supermarket plastic bags, melts at 130 degrees Celsius.
Is polyethylene autoclavable?
Yes, polyethylene is generally not autoclavable due to its low melting point and potential for deformation under high heat and pressure.
What is high melting point?
The melting point of a solid is the temperature at which it changes STATE from SOLID to LIQUID. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends (usually slightly) on pressure and is usually specified at STANDARDatmospheric pressure.
What is the melting point of polyethylene glycol 6000?
The melting point of polyethylene glycol 6000 is approximately 50-52°C.
Is calcium liquid at room temperature?
No it is a solid. Calcium has a high melting point. Most metals (except mercury) have high melting points.

What is the melting point of polyethylene?
Generally the melting point is from 248-266 degrees F. ( 120-130 C)
Is polythene a gas?
Polyethylene (polythene) is a waxy solid polymer formed from ethylene gas monomer under high temperature and pressures.
