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.
Which term is defined as the process by which a substance changes state from solid to liquid-?
melting
What is the melting point of polyethylene glycol 6000?
melting point of PEG 600 is form 55 -63 0C
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.
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 solid is very hard and has a very high melting point?
Tin
What is high 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?
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.
What temperature do Ziploc bags melt?
Quote: For common commercial grades of medium- and high-density polyethylene (Ziploc) the melting point is typically in the range 120 to 130 °C (250 to 265 °F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (220 to 240 °F).

A solid that has a high melting point and conducts electricity in solution is a?
metaloid
What physical change of a solid to a liquid at the melting point?
The physical change of a solid to a liquid at the melting point called melting.
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
