Since ice and water are in equilibrium, the temperature would be zero. When we heat the mixture, energy supplied is utilized in melting the ice and the temperature does not change till all the ice melts because of the latent heat of fusion. On further heating, the temperature of the water would increase.

Answer:
To determine the melting point of ice, the student immersed the thermometer bulb in crushed ice in a beaker and heated the beaker on a low flame. During this process, the student would observe that the temperature remains constant during the melting of ice.
Explanation:
Why does the temperature remain constant during the melting of ice?
The temperature remains constant during the melting of ice because the heat energy applied to the ice is used to break the intermolecular forces between the water molecules rather than increasing the temperature. This process is known as the latent heat of fusion. The temperature remains constant until all the ice has melted, and only then does the temperature start to increase again.
What happens during the process?
When the ice is initially placed in the beaker and heated, the heat energy from the flame is transferred to the ice. This heat energy is used to overcome the intermolecular forces between the water molecules, causing the ice to melt. However, as the ice is melting, the temperature remains constant at 0°C (32°F).
Why does the temperature remain constant?
The reason the temperature remains constant during the melting process is because the heat energy is being used to break the intermolecular forces that hold the water molecules together in a solid state. These forces require a certain amount of energy to be overcome, and this energy is provided by the heat source. As a result, the temperature does not increase until all the ice has melted.
What happens after all the ice has melted?
Once all the ice has melted, the temperature starts to increase. This is because the heat energy is now being used to increase the kinetic energy of the water molecules, causing them to move faster and increasing the temperature of the water.
In conclusion, when a student immerses the thermometer bulb in crushed ice in a beaker and heats the beaker on a low flame, they would observe that the temperature remains constant during the melting of ice. This is because the heat energy is being used to break the intermolecular forces between the water molecules rather than increasing the temperature.
