Define the latent heat of fusion of ice

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept**: The latent heat of fusion refers to the heat energy required to change a substance from solid to liquid at its melting point without changing its temperature.

2. **Definition**: The latent heat of fusion of ice is defined as the amount of heat required to convert 1 gram of ice at 0 degrees Celsius (the freezing point of water) into 1 gram of water at the same temperature (0 degrees Celsius).

3. **Temperature Reference**: This process occurs at the freezing point of ice, which is 0 degrees Celsius or 273 Kelvin.
