Question
Read the given statements and select the correct option.Statement 1: Phosphorus burns in air at room temperature.Statement 2: It is an example of spontaneous combustion.
Solution
Statement 1: Phosphorus does not burn in air at room temperature. It needs to be heated to a certain temperature to ignite. However, white phosphorus, a different allotrope of phosphorus, can ignite in air at room temperature.
Statement 2: Spontaneous combustion refers to the phenomenon where a substance can ignite without the application of any external heat source. Given that white phosphorus can ignite in air at room temperature, it can be considered an example of spontaneous combustion.
So, if the statements are referring to white phosphorus, both are correct. If they are referring to phosphorus in general, Statement 1 is incorrect while Statement 2 is correct.
