Q77 (CAPF/2014) Science & Technology › Basic Science (Physics, Chemistry, Biology) › Thermal physics Answer Verified

If a scientist reads an ambient temperature 273 K in the laboratory, what will a doctor’s thermometer read it ?

Result
Your answer:  ·  Correct: B
Explanation

The Kelvin scale is an absolute temperature scale where 273.15 K corresponds to the freezing point of water. In scientific and general contexts, 273 K is commonly approximated as 0 degrees Celsius. To convert Kelvin to Fahrenheit, the formula used is F = (K − 273.15)  9/5 + 32. Applying this to 273 K, the calculation yields approximately 31.73F. Since 273 K is the standard approximation for the freezing point of water, it aligns with 32 degrees Fahrenheit on the Fahrenheit scale. A doctor's thermometer, which typically uses the Fahrenheit scale in many regions or measures clinical ranges, would read this ambient laboratory temperature as 32F, representing the standard ice point.
