A cubical piece of heat-shield-tile from the space shuttle measures 0.17 m on a side and has a thermal conductivity of 0.065 J/(s·m·C°). The outer surface of the tile is heated to a temperature of 1050°C, while the inner surface is maintained at a temperature of 23°C. (a) How much heat flows from the outer to the inner surface of the tile in 3.0 minutes? (b) If this amount of heat were transferred to 1.5 liters (1.5 kg) of liquid water, by how many Celsius degrees would the temperature of the water rise?

Question

A cubical piece of heat-shield-tile from the space shuttle measures 0.17 m on a side and has a thermal conductivity of 0.065 J/(s·m·C°). The outer surface of the tile is heated to a temperature of 1050°C, while the inner surface is maintained at a temperature of 23°C. (a) How much heat flows from the outer to the inner surface of the tile in 3.0 minutes? (b) If this amount of heat were transferred to 1.5 liters (1.5 kg) of liquid water, by how many Celsius degrees would the temperature of the water rise?

The diagram illustrates a cube with sides labeled as "L," indicating equal length on all edges. It depicts a heat flow process where heat is applied to the bottom surface of the cube. An arrow labeled "Heat flow" is shown moving from the heated area at the bottom upwards through the cube. Next to the cube, there is a gas cylinder, connected to a nozzle aimed at the bottom of the cube, signifying a source of heat, likely a torch or burner. The heat source appears to heat the cube from the bottom, creating a gradient that indicates the direction of heat transfer within the material. This diagram is useful for visualizing heat conduction in a solid object and understanding how heat transfer occurs through direct contact with a heat source.
