You may need to download version 2.0 now from the Chrome Web Store. Flames are created at a given point in the combustion process, called the ignition stage. When a beam of white light enters a prism, it gets refracted and splits into its seven constituent colours. Cloudflare Ray ID: 5fc67b1caf98ee27 State one observation that indicates a chemical change has occurred in this investigation. fps the temperature of this part of the flame is around 1300°C, it is sufficient to melt gold at specific point and thus helps goldsmiths to give proper shape to the gold ornaments. When the oxygene feeding the combustion gets to the flame from air, the flame is called diffusion flame as in the case of the flame of a candle. Figure 5. Question 1. 10.
