The boiling point of water is 100 dregess?

Answer 1

Assuming that 100 dregess is your way of saying 100 degrees Celsius, it is the boiling point of pure water, under normal atmospheric pressure.

Answer 2

The boiling point of water is 100 degrees Celsius at standard atmospheric pressure. At higher altitudes where the atmospheric pressure is lower, the boiling point of water will be lower as well.
