When an ice cube is warmed only to the extent it has totally molten (...
- If the ambient temperature around a piece of ice increases, the temperature of the ice will increase as well. However, this steady increase in temperature stops as soon as the ice reaches its melting point.
- At this point, the ice undergoes a change of state and turns into liquid water, and its temperature will not change until all of it has melted.
- When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have the energy to break the bonds that hold them in a crystal structure.
- They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up. At a critical point – the melting point – they acquire enough energy to break free.
- When that happens, all the heat energy added to the ice is absorbed by H2O molecules changing phase.
- There's nothing left to increase the kinetic energy of the molecules in the liquid state until all the bonds holding the molecules in a crystal structure have been broke.
- Consequently, the temperature remains constant until all the ice has melted.
- Hence option (a) is the correct answer.

Explanation:
When an ice cube is heated to the extent that it completely melts, the temperature change during the entire process from the solid-state to the liquid state is as follows:
- Initially, the temperature of the ice cube increases. This is because heat energy is added to the ice cube, which increases the kinetic energy of the water molecules in the ice. As a result, the temperature of the ice cube increases.
- However, once the ice cube reaches its melting point, the temperature remains constant. This is because during the melting process, the heat energy is used to break the bonds between the water molecules in the ice cube. This process requires a lot of energy, and as a result, the temperature of the ice cube remains constant until all the ice is melted.
- Once all the ice has melted, the temperature of the water starts to increase again. This is because the heat energy is now being used to increase the kinetic energy of the water molecules in the liquid state.
Therefore, the correct answer is option 'A' - the temperature first increases and then remains constant during the process.
