b. When did the temperature change the slowest?
c. When did the temperature change the fastest?
d. Was the heat energy input constant?
e. Explain what was happening to the ice or water when the temperature was changing; a) the slowest or not at all b) the fastest?

Answer 1

In the given information, the temperature of the ice remains constant at 0°C while it is melting. It rises only after all the ice has melted.

Step-by-step explanation:

In the given information, Figure 10.26 shows the temperature changes of ice over time. After 10 minutes, the ice has absorbed enough heat to warm to 0°C and a small amount has melted. For the next 30 minutes, the ice continues to absorb heat but its temperature remains at 0°C while it melts. Only after all the ice has melted does the heat absorbed cause the temperature to increase to 22.2°C.

So, during the melting of the ice, the temperature remains constant at 0°C. This is because the heat energy being absorbed by the ice is used to break the intermolecular forces between the water molecules in the ice and convert the solid ice into liquid water, rather than causing a change in temperature.
