149361 Assertion: Specific heat of a body is always greater than its thermal capacity.
Reason: Thermal capacity is the heat required for raising temperature of unit mass of the body through unit degree.

149363 Assertion: A brass tumbler feels much colder than a wooden tray on a chilly day.
Reason: The thermal conductivity of brass is more than the thermal conductivity of wood.

149365 Three rods of the same dimensions have thermal conductivities $3 K, 2 K$ and $K$. They are arranged as shown in fig. with their ends at $100^{\circ} \mathrm{C}, 50^{\circ} \mathrm{C}$ and $20^{\circ} \mathrm{C}$. The temperature of their junction is

149366 Two identical rods of copper and iron are coated with wax uniformly. When one end of each is kept at temperature of boiling water, the length upto which wax melts are $8.4 \mathrm{~cm}$ and $4.2 \mathrm{~cm}$, respectively. If thermal conductivity of copper is 0.92 , then thermal conductivity of iron is
