500 g of Ice at 0 °C is kept in an insulated cubic box. The length of the box is 30 cm and the
thickness of the wall is 0.5 cm. The thermal conductivity of the wall is 0.04 W/mK. If the
environment temperature outside the box is 25 °C, Determine
(a) the rate of heat loss due to the heat conduction.
A closed box is filled with dry ice at a temperature of
-80.1 °C, while the outside temperature is 27.0 °C.
The box is cubical, measuring 0.383 m on a side, and
the thickness of the walls is 3.95 × 10-² m. In one day,
3.11 × 106 J of heat is conducted through the six
walls. Find the thermal conductivity of the material
from which the box is made.
