A cubical piece of heat-shield-tile from the space shuttlemeasures 0.09 m on a side and has a thernal conductivity of 0.065J/(s m C°). The outer surface of the tile is heated to atemperature of 1,219°C, while the inner surface is maintained at atemperature of 24°C.
(a) How much heat flows from the outer to theinner surface of the tile in 7.8 minutes?
Number: __________Â Â Units: __________
(b) If this amount of heat were transferred to3.2 litres (3.3 kg) of liquid water, by how many Celsius degreeswould the temperature of the water rise?
Take cwater = 4186 J/kg
Number: __________Â Â Units: __________
