what steps can you take to determine the melting point of a substance that sublimes before it melts?
Sublime occurs when a solid substance has a high vapor pressure. In this case, the melting point must be determined by using a sealed capillary tube to avoid loss of the sample.This can be achieved by heating the open end of the capillary tube, and with tweezers forcing it shut.
