Question

At high altitudes, water boils above ${100}^{°}C$.

• A. True
• B. False

Answer 1

The correct option is B False

1. Boiling point is directly proportional to pressure, when pressure increases boiling point increases and when pressure decreases boiling point also decreases.
2. At the sea level boiling point of water is ${100}^{°}C$ at $1atm$ pressure, below sea level pressure increases and hence boling point also increases.
3. Pressure decreases as altitude increases and as a result boiling point also decreases and will be below ${100}^{°}C$.

Hence, the given statement is false.
