It is therefore kept in water to prevent it from igniting. The ignition temperature of water is much higher than that of phosphorus, so it will not ignite while it is submerged in water.<\/p>\n<p>Option B is incorrect because the ignition temperature of phosphorus is actually very low. Option C is incorrect because the critical temperature of phosphorus is not particularly high. Option D is incorrect because the critical temperature of water is much higher than that of phosphorus.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;its ignition
