Discussion Overview

The discussion centers on the flammability of ethanol, exploring the underlying reasons for its high flammability. Participants are engaged in a homework-related inquiry, seeking to understand the chemical and physical principles that contribute to ethanol's behavior in combustion scenarios.

Discussion Character

  • Homework-related, Conceptual clarification, Exploratory

Main Points Raised

  • One participant asks why ethanol is highly flammable and expresses difficulty finding information on the topic.
  • Another participant suggests considering the conditions necessary for a substance to be classified as "flammable."
  • A different participant acknowledges the need for ethanol to react with oxygen but expresses uncertainty about the details.
  • Another response prompts consideration of reaction kinetics as a factor in flammability.
  • One participant notes that while ethanol must react with oxygen, not all reactions with oxygen result in flames, highlighting the importance of the reaction rate.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific reasons for ethanol's flammability, and multiple viewpoints regarding the necessary conditions for flammability are presented.

Contextual Notes

Participants have not fully defined the conditions or mechanisms that contribute to flammability, leaving some assumptions and details unresolved.

The Attempt at a Solution



I know the chemical is highly flammable, but why is it? Can't find anywhere on the web why it is so flammable.

Thanks!
 
Physics news on Phys.org
There are several conditions that have to be meet for the substance to be "flammable" - can you think what they are?

err? It has to react with Oxygen? Sorry, I'm brainless right now lol. Please tell me lol :D
 
Think about reaction kinetics.

Hey? So basically, why is Ethanol flammable, briefly.
 
It doesn't just have to react with oxygen...

Iron reacts with the oxygen in air, but we do not call that a flame, because it doesn't happen fast enough.
