Question

At atmospheric pressure, the water boils at ${100}^{\circ }C$. If pressure is reduced, it will boil at

• A. Higher temperature
• B. Lower temperature
• C. At the same temperature
• D. At critical temperature

Answer 1

The correct option is B Lower temperature

It is known that Boiling Point is proportional to pressure.

When pressure decreases, boiling point also decreases.

so If pressure is reduced, it will boil at Lower temperature
