Conversion of ice to solid is endothermic reaction. True/False?

Explanation

To determine whether the statement "Conversion of ice to solid is an endothermic reaction" is true or false, we need to analyze the process involved in the conversion of ice (solid) to water (liquid) and then back to solid.

### Step-by-Step Solution:

1. **Understanding Endothermic Reactions**:
- An endothermic reaction is defined as a process that absorbs heat from its surroundings. The term "endo" means "within" or "inside," and "thermic" refers to heat.

2. **Phase Changes**:
- The conversion of ice (solid) to water (liquid) is a phase change that requires energy. In this process, heat is absorbed to break the strong intermolecular forces that hold the solid structure of ice together.

3. **Conversion of Ice to Water**:
- When ice is heated, it absorbs heat energy from the surroundings. This energy is used to overcome the intermolecular forces in the ice, allowing it to transition into the liquid state (water). Therefore, this process is endothermic.

4. **Conversion of Water to Ice**:
- Conversely, when water freezes to become ice, it releases heat to the surroundings. This process is exothermic because the energy is released as the water molecules lose kinetic energy and form a solid structure.

5. **Conclusion**:
- The statement in question refers to the conversion of ice to solid. Since ice is already a solid, the conversion of ice to solid does not involve any heat absorption. Instead, it is the reverse process of melting (ice to water) that is endothermic. Therefore, the statement "Conversion of ice to solid is endothermic reaction" is **False**.

### Final Answer:
**False** - The conversion of ice to solid is not an endothermic reaction; it is an exothermic process.
