A
White phosphorus is highly reactive and has a very low ignition temperature. It spontaneously ignites at about 30 °C in air. So if the room temperature is more than 30 °C, then it would catch fire.
It burns with a white flame producing clouds of white smoke. It is usually stored under water to prevent exposure to air.
