Correct option is B
The correct answer is (b) 100°C
The boiling point of water at standard atmospheric pressure (1 atm or 101.3 kPa) is 100°C. At this temperature, water transitions from the liquid phase to the gaseous phase.
Additional Information:
- Kelvin is the base unit of temperature in the SI system.
- Atmospheric pressure is the force exerted on a surface by the air above it as gravity pulls it to Earth.
- It is commonly measured with a barometer.
- Fahrenheit Conversion:
Using the relation F = (9/5)C + 32, the boiling point of water is 212°F (at standard atmospheric pressure).
