The ends of a long bar are maintain different temperatures and there is no loss of heat from the sides of the bar due to conduction or radiation The graph of temperature against distance of the bar when it has attained steady state is shown here The graph shows Temperature Distance from hot end i the temperature gradient is not uniform ii the bar has uniform cross sectional area iii the cross sectional area of the bar increases as the distance from the hot end increases iv the cross sectional area of the bar decreases as the distance from the hot end increases 1 i ii 2 i iii
