The manipulated variable was the element being tested. These they will place into a flame in order to observe the colors produced. Gas-discharge tubes for hydrogen, helium and mercury are set up at the front bench. As many elements will still produce distinctive colors under such conditions, simple flame tests can be used to identify these elements. For the same radio station, calculate the energy (E) in kilojoules, kJ. It can be in the form of light, an electric discharge, or heat. Digital Flame Take a look at Lab Reply Key. The result is called a line emission spectrum, and can serve as a fingerprint of the element to which the atoms belong.
