Question

A calorimeter is designed to act like a thermos flask. Which feature of the calorimeter is primarily responsible for this thermal isolation?

विकल्प

• The copper inner vessel

• The metal stirrer

• The insulating outer jacket and air gap

• The glass thermometer

Answer 1

The insulating outer jacket and air gap

Explanation:

Just as a thermos flask uses an insulating layer to trap heat, the calorimeter uses an insulated outer jacket combined with an insulating air gap between the inner and outer vessels. Together, these prevent heat from escaping to the surroundings, ensuring accurate measurement.
