Water has high specific heat due to

Options

A. Its dipole nature
B. Smaller angle between hydrogen atoms and oxygen atom
C. Hydrogen bonds amongs molecules
D. All the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Specific Heat**:
- Specific heat is defined as the amount of heat energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius. Water has a high specific heat compared to other liquids.

2. **Identifying the Factors**:
- The question asks for the reason behind the high specific heat of water. The options provided are:
- A) Dipole nature
- B) Small angle between hydrogen and oxygen atoms
- C) Hydrogen bonds among molecules
- D) All of the above

3. **Analyzing the Options**:
- **Dipole Nature**: Water is a polar molecule due to the difference in electronegativity between hydrogen and oxygen, which contributes to its properties but is not the primary reason for high specific heat.
- **Small Angle Between Hydrogen and Oxygen Atoms**: While the molecular structure of water is important, the angle itself does not directly explain the high specific heat.
- **Hydrogen Bonds Among Molecules**: This is the key factor. Water molecules are held together by hydrogen bonds, which require significant energy to break. When heat is added, much of that energy goes into breaking these bonds rather than increasing the temperature.

4. **Conclusion**:
- The correct answer is that the high specific heat of water is primarily due to the hydrogen bonds among the molecules. Therefore, the best option is C) Hydrogen bonds among molecules.

5. **Final Answer**:
- Water has high specific heat due to hydrogen bonds among molecules.
