When ice melts to form water, energy is absorbed. This process is known as endothermic because it requires energy input to occur. Let's explore this in more detail.

Ice Melting Process
When ice is exposed to a temperature above its melting point (0 degrees Celsius or 32 degrees Fahrenheit), it begins to absorb heat energy from its surroundings. The heat energy causes the ice molecules to vibrate more rapidly, breaking the attractive forces between them. As a result, the solid ice transforms into liquid water.

Endothermic Process
The melting of ice is an example of an endothermic process. In an endothermic process, energy is absorbed from the surroundings to break the bonds holding the particles together. This absorption of energy causes the surroundings to cool down. When ice melts, it absorbs a specific amount of heat energy from its surroundings to overcome the forces of attraction between its molecules.

Heat Energy Absorption
During the ice melting process, heat energy is absorbed from the surroundings. This energy is used to break the hydrogen bonds between water molecules in the ice. The hydrogen bonds are relatively strong forces of attraction that hold the solid ice together in a structured lattice.

Temperature Change
When ice absorbs heat energy, its temperature remains constant at 0 degrees Celsius until all the ice has melted. This is because the absorbed energy is being used to overcome the intermolecular forces and transform the solid ice into liquid water. Once all the ice has melted, any additional heat energy will cause the temperature of the water to rise.

Importance
The absorption of energy during the ice melting process is essential for the water cycle and the Earth's climate regulation. When ice melts, it helps regulate the planet's temperature by absorbing heat energy from the surroundings. It also plays a crucial role in maintaining the water cycle, as melted ice contributes to the formation of rivers, lakes, and oceans.

In conclusion, when ice melts to form water, energy is absorbed from the surroundings. This process is known as endothermic because it requires an input of energy. The absorbed energy is used to break the hydrogen bonds between water molecules and transform the solid ice into liquid water.

Introduction:
When ice melts to form water, energy is absorbed. This process is called endothermic because it requires heat energy to break the bonds between the water molecules in the ice and convert it into liquid water.

Explanation:
When ice is exposed to a higher temperature, such as room temperature or above, the heat energy from the surroundings is transferred to the ice. This causes the water molecules in the ice to gain energy and vibrate more vigorously. As a result, the bonds holding the water molecules together in a solid lattice structure start to weaken.

Melting Process:
During the melting process, the heat energy absorbed by the ice is used to break the intermolecular forces between the water molecules. These forces are responsible for holding the molecules in a fixed position within the solid ice lattice.

Breaking of Bonds:
As the ice absorbs more heat energy, the water molecules gain enough energy to break free from their fixed positions and move more freely. This breaking of bonds allows the water molecules to slide past each other and form a less organized arrangement, resulting in the formation of liquid water.

Energy Absorption:
The energy absorbed during the melting process is used to overcome the attractive forces between the water molecules and break the bonds. This energy is stored within the water molecules in the form of potential energy, allowing them to move more freely in the liquid state.

Conclusion:
In conclusion, when ice melts to form water, energy is absorbed from the surroundings. This energy is used to break the intermolecular bonds between the water molecules in the ice, allowing them to transition from a solid to a liquid state. Therefore, the correct answer is option 'D' - energy is absorbed.
