The heating curve of an unknown substancce shows that the temperature rises steadily, then stays constant at 15 degrees C for a while. The temperature then starts increasing again for a while. However, at 234 degrees C, the temperature stays constant for quite some time. At what temperature does this substance melt? At what temperature does it vaporize (boils) ?
