Question

The range of clinical thermometers is:

• A. ${50}^{\circ }C-{100}^{\circ }C$
• B. $-{10}^{\circ }C-{110}^{\circ }C$
• C. ${100}^{\circ }C-{142}^{\circ }C$
• D. ${35}^{\circ }C-{42}^{\circ }C$

Answer 1

The correct option is D

${35}^{\circ }C-{42}^{\circ }C$

A clinical thermometer is used to measure body temperature. For a healthy person, normal body temperature usually do not fall below ${35}^{\circ }C$ or rise above ${42}^{\circ }C$. Therefore, the range of clinical thermometer is ${35}^{\circ }C-{42}^{\circ }C$.
