Can someone help me i need the answer for numbers 2,3 and 4
Experiment Two Melting and Boiling Points Prelaboratory Quiz Name Laboratory Section 1. Two groups of students prepared the compound acetamide. Group A isolated a soll wi th a melting point of 80.5'C. Group B obtained a compound with a melting po of 74-77 C. When the students consulted the chemistry manual, acetamide was found to havea melting point of 82°C. Which group prepared a more pure compound? And why: The melting point of a solid may be defined as the temperature when both solid and liquid phases coexist. How may you define the boiling point of a substance? 2. 3. The boiling point of liquid is determined by heating it slowly and recording the tem- perature when the liquid vaporizes. Suppose a student doing the experiment heats the liquid up very rapidly, is he likely to get the correct boiling point? Explain. The boiling point of a liquid depends on the pressure of its vapor over the liquid. Therefore the boiling point of water at the top of the Himalayan mountain is less than 100°C. What is the melting point of ice on top of the Himalayan mountain? 4.
