The ends of a metallic bar are maintained at different temperature and there is no loss/gain of heat from the sides of the bar due to conduction or radiation. In the steady state the temperature variation along the length of the bar is a shown in the figure what do you think about the cross sectional area of the bar?

The ends of a long bar are maintained at 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 (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 becreases as the distance from the hot end increases

The ends of a thin bar are maintained at different temperatures. The temperature of the cooler end is 11^(@)C , while the temperature at a point 0.13m from the cooler end is 23^(@)C and the temperature of the warmer end is 48^(@)C . Assuming that heat flows only along the length of the bar ( the sides are insulated), find the length of the bar.
