Question

Complete the following statement: The interior of a thermos bottle is silvered to minimize heat transfer due to
A. conduction and convection
B. conduction
C. conduction, convection and radiation
D. conduction and radiation
E. radiation.

Answer 1

Answer:

E. radiation.

Explanation:

As we know that heat transfer due to conduction depends on thermal conductivity of the materials and heat transfer due to convection depends on the velocity of the fluid.But on the other hand heat transfer due to radiation depends on the surface properties like  emmisivity .So when bottle is silvered then it will leads to minimize the radiation heat transfer.

Therefore answer is --

E. radiation.
