Answer 2

Answer:

The silver coating on the inner bottle prevents heat transfer by radiation, and the vacuum between its double wall prevents heat moving by convection. The thinness of glass walls stops heat transfer by conduction. The case surrounding the flask provides additional insulation.

Explanation - Heat loss due to conduction is prevented by placing the calorimeter box in a well-lagged vessel using wool or cork material. Heat loss due to convection is prevented by placing a lid on the box. Heat loss due to radiation is minimized by polishing the box in order to smoothen it.
