A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

This is inaccurate. Graphite is not flammable. It forms small particles that, mixed with air, could combust in a dust explosion, just like flour.
I'm probably just being dense but what's the difference between being flammable and being susceptible to combustion?
You're not dense for asking a question. Without asking questions, it's Impossible to learn.
The flash point is different. The flash point is the temperature that is necessary to create enough vapor for the substance to ignite.
Flammable material has a low flash point, which means it catches on fire easily. Think gasoline. Combustibles need a higher initial temperature, but eventually they will burn and sustain the burning until running out. Think wood.
Makes perfect sense, thank you
