A group of students went for an excursion to Shimla in the month of November. A science teacher also accompanied them. There the temperature fell to `-10^(@)C`. They took some ice cubes and subjected them to heating while keeping a thermometer in the container. The students monitored the readings of thermometer till the entire ice melted into water. All of them went to their science teacher and showed him their observations. He asked them to discuss among themselves and give a proper justification for the observations on the readings at various stages.

Explanation

To analyze the observations made by the students while heating ice cubes, we can break down the process into several stages:

### Step 1: Initial Temperature
- **Observation**: The initial temperature of the ice cubes is at `-10°C`.
- **Justification**: At this temperature, the ice is solid and below the freezing point of water. The thermometer shows this low temperature.

### Step 2: Heating the Ice
- **Observation**: As the students start heating the ice, the thermometer initially does not register a rise in temperature.
