a student obtained a solid product in a laboratory synthesis. to verify the identity of the solid, she measured its melting point and found that the material melted over a 12 degree Celsius range. after it had colled, she measured the melting point of the same sample again and found that this time the solid had a sharp melting point at the temperature that is characteristic of the desired product. why were the two melting points different? ehat was responsible for the change in the melting point?
