Classify the following processes as exothermic or endothermic.
Molten metal solidifies

Explanation

To classify the process of molten metal solidifying as exothermic or endothermic, we can follow these steps:

### Step 1: Understand the Definitions
- **Exothermic Process**: A process that releases heat to the surroundings. This means that during the reaction or phase change, energy is given off.
- **Endothermic Process**: A process that absorbs heat from the surroundings. This means that energy is required for the reaction or phase change to occur.

### Step 2: Analyze the Process
- The process in question is the solidification of molten metal. When a substance changes from a liquid state to a solid state, it typically involves the release of heat.
