Question

A casserole minimises heat transfer by ______.

• A. conduction
• B. convection
• C. radiation
• D. All of the above.

Answer 1

The correct option is D All of the above.

Casseroles are designed to minimise the heat transfer by conduction, convection, and radiation.
The walls of the casserole are made of a heat insulating material to prevent conduction. The puff layer between the inner and outer pots prevents the heat transfer from convection, and radiation is prevented by the mirrorred finish given to the inner walls of the inner pot.
