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.

A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true and statement 2 is false.
D Both statements 1 and 2 are false.


I say it is option a but they say it is b....But isn’t this definitely due to spontaneous combustion?

Hi, the statement 2 is true but just tells about the type type combustion to which the reaction given in statement belong. it does not tell about actual cause of burning of phosphorus in air at room temperature. the reason for statement 1 is that phosphorus is a highly reactive element that's why burns in air at room temperature.

Acclimatization and adaptation mean two totally different things. Adaptation means permanent adjustment to our habitat whereas acclimatization means temporary adjustment to a place where we temporarily stay for some time and get used to. In my opinion, option A is the right answer.

Ans 8:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 9:

Class : Class 6
The answer is A. You should Read the book twice again. But even then also you think that the answer is B than the book is a spam. Adaptation is the permanent feature of an organism which helps it to survive in its habitat, while acclimatisation is a temprory feature or change in feature of an organism which helps it to survive in any other place rather than its habitat......................................................................
