Flames are hot enough to have ionized gaseous components of sufficient density they are then considered ______
plasma
When a lighter is held to a candle, the applied heat causes the fuel molecules in the candle wax to ______
vaporize
In this state they can then readily react with oxygen in the air, which gives off enough heat in the subsequent exothermic reaction to vaporize yet more fuel, thus sustaining a consistent ______
flame
The high temperature of the flame causes the vaporized fuel molecules to decompose, forming various incomplete combustion products and free ______
radicals
Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a ______ is held to a candle
lighter
