Why is the mass of (for example, medical) thermometer always small?
| February 6, 2021 | education
A large thermometer would have two disadvantages:
1. It would take a long time to equalize the temperature of the thermometer and the temperature of the measured body.
2. With comparable masses of the thermometer and the measured body, an equilibrium temperature would be established, which would differ significantly from the true body temperature.
Answer: The small mass of the thermometer allows you to quickly measure the temperature and almost not affect the temperature of the measured body.
