Rubber begins to melt at approximately 180 degrees Celsius. At low temperatures, around 5 C to 6 C, there is a risk that rubber hardens because of crystallization. The optimum temperature for rubber is 20 C.
The melting point of lead in Celsius is 327.46o. Temperature Fahrenheit = Temperature Celsius(1.80) + 32 Temperature Fahrenheit = (327.46o C)(1.80) + 32 = 621.43o Fahren â¦ heit ==.elting temperature is the point where a substance is reduced to a liquid (this is the state it changes to). the usual melting point of substances is 100 degrees or higher. â¦   thank you for answering!! 6 people found this useful. 1  The Periodic Table of Elements Life is sustained by a number of chemical elements.
