A cylindrical rod having temperature

{T_1}

and

{T_2}

at its ends. The rate of flow of heat is

{Q_1}\,\,cal/s

. If all the linear dimensions are doubled keeping temperature constant then rate of flow of heat

{Q_2}

will be

View answer and explanation

Correct option: B

2{Q_1}

Option B (

2{Q_1}

) is correct because doubling the linear dimensions while keeping the temperature constant doubles the rate of heat flow.
