Signs and Symptoms. Because the signs of AS can be similar to those of other behavioral problems, it's best to let a doctor or other health professional evaluate a child's symptoms. Many kids are diagnosed with attention deficit hyperactivity disorder (ADHD) before a diagnosis of AS is made later.
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.
Confidence votes 25. Steel often melts at around 1370 degrees C (2500 Â°F). This varies depending on the specific steel alloy. The specific heat of steel varied from 420J/KG/Deg C at room temperature to 720J/KG/Deg C at 1535 deg C. This equates to a theoretical heat requirement of approximately 375KWh/mt to melt steel from room temperature. In practice, foundries use between 500 and 800 KWh /mt to raise steel to a little above its melting point of 1535deg C.
