1.	Assertion (A) : The temperature at which vapour pressure of a liquid is equal to the external pressure is called boiling temperature. Reason (R ) : At high altitude, atmospheric pressure is high.
Answer» Both A and R are TRUE and R is the correct explanation of A. Both A and R are true R is not the correct explanation of A. A is true but R is FALSE. A is false but R is true. Solution :Correct R. At high altitude, atmospheric pressure is LOW.
