At what temperature does water catch fire?
Boiling water doesn’t start fires. Water boils at around 100 degrees Celsius or 212 degrees Fahrenheit. There’s not much that has an auto-ignition point below this temperature (and as boiling water has no flame, only the heat from the water could cause a fire).
