| The energy content of coal varies depending on the water content and sulfur contaminates within the coal. Burning coal produces the greenhouse gasses such as carbon dioxide. In addition, the burning of coal produces sulfur dioxide and nitrogen oxides which contribute to smog and acid rain. This laboratory experiment measures CO2 emissions from various types of coal using CBL probes and graphing technologies. Using a Bunsen burner, a ring stand and wire gauze, four types of coal are burned, the gaseous material entrapped using an inverted funnel.
