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 altituded 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 but R is not the correct explanation of A A is true but R is false. A is false but R is true. Solution :Assertion is true but REASON is false. At HIGH ALTITUDE, atmospheric pressure is low.
