Question

question 7
how long does it take a bimetallic stemmed thermometers reading to steady after it is inserted into food?
5 seconds
10 seconds
15 seconds
30 seconds

Explanation:

Bimetallic stemmed thermometers are commonly used in food - related temperature measurements. Their design and heat - transfer characteristics mean that it takes a certain amount of time for the bimetallic strip (which is the sensing element) to reach thermal equilibrium with the food. Through practical use and calibration in food - handling and cooking contexts, it has been determined that 15 seconds is the typical time for the reading to stabilize.

Answer:

15 seconds
