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.
Answered by The Community. Making the world better, one answer at a time. Depending on the composite of the concrete material, it can melt at different temperatures. When concrete reaches a high enough temperature such as more than 1000 degrees Celsius, it can crumble like sugar.ot everything that is solid at room temperature and normal atmospheric pressure will melt by simply raising the temperature-some things convert directly to gas (sublimate)a â¦ nd some things will decompose or react to other substances before melting (burning is one type of reaction), to answer part of the question.
