Assertion : It is hotter over the top of a fire than at the same distacne of the side.
Reason : Air surrounding the fire conducts more heat upward

(A) : It is hotter over the top of a fire than at the same distance on the sides. ( R) : Air surrounding the fire conducts more heat upwards.

It is hotter over top of the fire than at same distance on the sides due to

Assertion It is hotter over the top of a fire than at the same distance on the sides . Reason In the upwared direction , the heat propagate through convection.

Assertion It is hotter over the top of a fire than at the same distance on the sides . Reason In the upwared direction , the heat propagate through convection.

Assertion: Air at some distance above the fire is hotter than the same distance side wise. Reason: Air surrounding the fire carries heat upward due to conventional current.

Assertion: Air above the fire at some distance is hotter than the air below it at the same distance. Reason: Air surrounding the fire carries more heat upwards than downwards.
