1.	Assertion : The normal boiling point of water is 100 C^(@) and standard boiling point of water is 99.6 C^(@) .Reason : The temperature at which vapour pressure of liquid is equal to the external pressure is called boiling temperature at that pressure .
Answer» If both assertion and reason are true and reason is the CORRECT explanation of assertion . If both assertion and reason are true but reason is notthe correct explanation of assertion . If assertion is true but reason is false . If both assertion and reason are false . SOLUTION :At 1 atm pressure, BOILING temperature is called normal boiling point and if pressure is 1 BAR then the boiling point is called standard boiling point of the liquid. 1 bar pressure is slightly less than 1 atm pressure therefore, standard boiling point of the liquid is slightly LOWER than the normal boiling point.
