1. Two metal rods A and B of same size are arranged
as shown in the figure. The extreme ends of the
combination are maintained at the indicated
temperatures. The arrangement is thermally
insulated. The coefficients of thermal conductivity
of A and B are 300 W/m°C and 200 W/m°C,
respectively. After steady state is reached, the
temperature of the interface will be

of a bucket full of water at 2°C. If the temperature
of the water is increased to 3°C, the buoyant force
on the sphere due to water will

(2) Be unchanged
(3) Decrease
