Final answer:

The melting temperature of ice decreases with increased pressure, thus at 0.01 atm it would be below 0°C. The boiling temperature of water at 0.01 atm would be significantly lower than 100°C.

Step-by-step explanation:

To answer the student's question about the melting and boiling temperatures of water at a pressure of 0.01 atm, we need to analyze the phase diagram of water. In the case of melting ice at very low pressures, the phase diagram indicates that the melting temperature of ice decreases with increased pressure.

Since the pressure given is extremely low (0.01 atm), the melting temperature would be below 0°C, close to the triple point of water. However, we don't have a direct value from the data provided, and typically, phase diagrams don't extend to such low pressures.

On the other side, the boiling point of water at 0.01 atm is not specified, but it would certainly be at a much lower temperature than 100°C which is the standard boiling point at 1 atm as boiling takes place when the vapor pressure of the liquid equals the external pressure.
