Heat is absorbed

Explanation:
When ice is converted into water, heat is absorbed. This process is known as melting or fusion. It occurs when the temperature of the ice reaches its melting point, which is 0 degrees Celsius or 32 degrees Fahrenheit.

Heat transfer and phase change:
Heat transfer occurs when there is a difference in temperature between two objects or substances. It flows from a higher temperature region to a lower temperature region. During a phase change, such as melting, the transfer of heat leads to a change in the state of matter.

Endothermic process:
The conversion of ice into water is an endothermic process. This means that it requires heat energy to break the intermolecular forces holding the ice molecules together in a solid lattice structure. As the heat is absorbed, the kinetic energy of the ice molecules increases, causing them to vibrate more rapidly.

Melting point:
The melting point of a substance is the temperature at which it changes from a solid to a liquid phase. In the case of ice, the melting point is 0 degrees Celsius or 32 degrees Fahrenheit. At this temperature, the ice absorbs heat energy from its surroundings, causing the solid ice to melt into liquid water.

Breaking intermolecular forces:
The intermolecular forces between the water molecules in ice are relatively strong, keeping them in a solid state. As heat is absorbed, the energy is used to break these intermolecular forces, allowing the molecules to move more freely and transition into a liquid state.

Temperature and phase change:
During the phase change from ice to water, the temperature remains constant at the melting point until all the ice has melted. This is because the absorbed heat energy is used to overcome the intermolecular forces and change the state of the substance rather than increasing its temperature.

Conclusion:
In conclusion, when ice is converted into water, heat is absorbed. This process is endothermic and requires the input of heat energy to break the intermolecular forces holding the ice molecules together. The temperature remains constant at the melting point until all the ice has melted.
