The Claim
Water boils at 100 degrees Celsius at a pressure of 1 atmosphere.
Water’s accepted normal boiling point is approximately 100°C at a pressure of 1 atmosphere. Modern temperature scales and precise measurements can produce values differing by a few hundredths of a degree, but that minor technical variation does not change the standard scientific statement.

Claim:
Pure water boils at 100 degrees Celsius at sea level (standard atmospheric pressure).
NOT BS
Claim:
Water can simultaneously boil and freeze under specific pressure conditions.
HARDLY BS
