In which of the following, heat energy will be given?

Options

A. Electrolysis of water
B. Dissolution of ammonium chloride in water
C. Burning of L.P.G.
D. Decomposition of silver bromide in the presence of sunlight

Explanation

To determine in which of the following processes heat energy will be given, we will analyze each option provided:

1. **Electrolysis of Water**:
- In this process, water (H2O) is broken down into hydrogen (H2) and oxygen (O2) gases using electric energy.
- The reaction does not release heat; instead, it requires an external source of energy (electricity) to proceed.
- **Conclusion**: Heat energy is not given in this process.

2. **Dissolution of Ammonium Chloride (NH4Cl)**:
