WebThe definition for a flammable solid can be based on the temperature or on the simple observation that any solid that burns immediately on exposure to a naked flame, spark or friction is flammable. This means that you can’t easily define whether something is “flammable” and expect another person to understand exactly what you mean by … Web13 jul. 2024 · The next chemical property is flammability, which measures the ability to combust. Through flammability, we can see if the matter will burn once we expose it to fire. Burning is a chemical reaction, and by placing matter under it, we can determine how flammable it is, and how quickly it will burn.

WebThe Flammable Range (also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced.. Three basic requirements must be met for explosion to take place: flammable substance - fuel; oxidizer - oxygen or air; source of ignition - spark or high heat WebIf the liquid has a low boiling point it will be volatile, that is it will evaporate easily. If it evaporates easily then above the liquid will be lots of vapour. If the liquid has a high boiling point it will not be volatile and there will be very few vapour (gas) particles above the liquid.
