If you did have pure graphite to burn, a simple flame wouldn't be hot enough to combust it. You need to sustain temperatures of around 1000 − 2000 ∘ C in order for pure carbon to burn.

[@dominoartist4545]

18:15 We would use a Fire Extinguisher because water is a good conductor of electricity...Therefore if we use water chances are that we can get electric shock.😊😊

[@Avataryt07]

Legend's seeing comments for time pass 😂😂😂😂

[@Lionx23290]

Option b (fire extinguisher)
Because if we put water it can give us a shock or current. But fire extinguisher will produce carbon dioxide and that will cut the connection between oxygen and fire and help to stop the fire.

[@ASayush13]

19:23

[@gouriverma_op]

18:39 b option is correct

[@anshsingh6604]

The answer is fire extinguisher because if we use water then we got an electrical shock 🤯

[@SanjayKumar-zu3uk]

The auto-ignition temperature of LPG ranges from approximately 410 to 580 degrees Celsius, indicating that it does not spontaneously ignite under typical temperature conditions. However, entrapped air within the vapor poses a significant hazard during pumping or filling operations if the vessel or cylinder has not been properly purged.

[@rkdhankhar6845]

Thanks sir for explaining tommoro is my exam ❤❤

[@SunilYadav-it5yh]
