Athermos bottle reduces energy loss due to radiation reduces energy loss due to conduction reduces energy loss due to convection all of the above

all of the above

Option (d) is the correct answer.

Explanation:

A thermos bottle is defined as a bottle which has vacuum between inner and outer wall so that the material will keep warm.

Therefore, in a thermos bottle there will be reduction in energy loss due to radiation, conduction and convection.

Thus, we can conclude that a thermos bottle is all of the above.
