Question

State whether the given statement is True or False

The upper standard point of a thermometer is $273K$.

• A. True
• B. False

Answer 1

Answer: (B)

The correct option is (B) False.

The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. The melting point of ice is $0^{\circ }C=273K$

The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure. The boiling point of water is ${100}^{\circ }C=100+273=373K$

Thus, the given statement is false.
