Flaming Vapor Ramp: Safety Demonstration—ChemTopic™ Lab Activity


Vapors from volatile, flammable liquids are generally heavier than air and can travel along a countertop to an ignition source. In the Flaming Vapor Ramp: Safety Demonstration—ChemTopic™ Lab Activity, the necessity for safety is demonstrated as vapors are ignited and their flames quickly follow the vapor trail back to the vapor source, which may result in a very large fire or explosion. Available as part of the Chemistry of Gases—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
