False. While the Sun appears as a bright, hot sphere, it's not a ball of fire in the traditional sense. The Sun is primarily composed of hot gases, primarily hydrogen and helium, and its heat and light are generated by nuclear fusion, not combustion. Here's why:No oxygen for combustion: Fire requires oxygen, which is not present in the vacuum of space. Nuclear fusion: The sun's core undergoes nuclear fusion, where hydrogen atoms combine to form helium, releasing enormous amounts of energy. Plasma state: The extreme heat in the sun causes the gases to exist as plasma, a superheated state of matter different from a fire.
