**Step-by-Step Solution:** 1. **Understanding the Flames**: The question asks about the color of the flames produced by an LPG stove and a Bunsen burner. Both of these flames are noted for their blue color. 2. **Identifying the Type of Combustion**: The flames of both the LPG stove and the Bunsen burner are a result of complete combustion. This means that the fuel (LPG in the case of the stove, and gas in the case of the Bunsen burner) burns in the presence of sufficient oxygen. 3. **Role of Oxygen Supply**: In both cases, there is an excess supply of oxygen. This excess oxygen is crucial for ensuring that the combustion process is complete. ...
