Question

Choose the incorrect option based on the data provided in the table.​​

Place	Altitude	Boiling Point
A	_____	Highest
B	Moderate	_____
C	_____	Lowest

• A. The boiling point of B lies in ​between those of A and C.​
• B. Pressure is ​minimum at B.​
• C. Pressure is ​maximum at A.
• D. Pressure is ​minimum at C.

Answer 1

The correct option is B

Pressure is ​minimum at B.​

As altitude of a region increases, the atmospheric pressure of that region decreases. Consequently, the boiling point of a liquid decreases.

• Place A has highest boiling point. This signifies that it has highest atmospheric pressure.
• Place B is at medium altitude so the atmospheric pressure at B will be moderate . Consequently, its pressure will also be moderate.
• Place C has lowest boiling point. This signifies that it has lowest atmospheric pressure.

Hence, the incorrect statement is option (d).
