Question

Water at normal atmospheric pressure boils at :

• A. $0^{\circ }C$
• B. ${100}^{\circ }C$
• C. $250K$
• D. ${50}^{\circ }C$

Answer 1

The correct option is B ${100}^{\circ }C$

Boiling occurs when the vapor pressure exceeds the surrounding pressure from the atmosphere. At standard atmospheric pressure, water boils at approximately ${100}^{0}C$.
