To determine whether each process is endothermic or exothermic, we look at whether the system absorbs or releases heat.
1. **A fire (the system is the fire)**:
- **Exothermic**: A fire releases heat into the surroundings as a result of combustion. Therefore, it is considered an exothermic process.
2. **A car engine (the system is the engine)**:
- **Exothermic**: A car engine burns fuel which generates heat as a byproduct of combustion. This heat is released into the environment, making the process exothermic.
3. **A melting ice sculpture (the ice is the system)**:
- **Endothermic**: When ice melts, it absorbs heat from its surroundings to change from solid to liquid. Therefore, the melting of the ice sculpture is an endothermic process.
In summary:
- Fire: Exothermic
- Car engine: Exothermic
- Melting ice sculpture: Endothermic
