You're telling me that if you threw a pan of boiling grease into the water it would grow hotter and hotter? From what I understood, water is only ineffective against grease fires because it can cause the grease to splatter, causing severe burns. But in a lake?...
But you're the chemistry major. You would know.
Well, in the situation of JUST ONE PAN'S WORTH of grease fire into A WHOLE LAKE, I'd suppose you'd be right. HOWEVER, I noted the fact that water doesn't work on grease fires so our forum members wouldn't make the MISTAKE of trying to put out a HOUSEHOLD GREASE FIRE with WATER OR a WATER-EMITTING FIRE EXTINGUISHER!!! I just wanted to protect the safety of our forum members.
The CORRECT WAY to put out a grease fire is with a CARBON DIOXIDE FOAM EMITTING FIRE EXTINGUISHER!!!Ed, you're right! Using water on a grease fire WILL help spread the fire by spreading out the burning grease! However, the
OTHER REASON that using water on a grease fire is wrong is because the grease, as well as the immense heat, causes water to break down into Hydrogen and Oxygen gasses. And, as everyone here should know, hydrogen and oxygen gases fuel fires.
