A cubical piece of heat-shield-tile from the space shuttle measures 0.13 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 1230°C, while the inner surface is maintained at a temperature of 22°C. (a) How much heat flows from the outer to the inner surface of the tile in 6.0 minutes? (b) If this amount of heat were transferred to 3.2 liters (3.2 kg) of liquid water, by how many Celsius degrees would the temperature of the water rise? (a) Number Units Heat flow
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.

**Diagram Explanation:**
The diagram depicts a cubical heat-shield tile with each side labeled with a length 'L', indicating the dimensions. A heat flow is shown moving from the bottom to the top through the tile, represented by an arrow labeled "Heat flow." One side of the cube is colored with a gradient to visually indicate a variation in temperature. The image also includes a representation of a gas cylinder connected to the tile, illustrating the concept of heat transfer in the exercise.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd452bd8c-7554-4806-a6d8-accf0f380aea%2F46f59d1d-02c5-462a-8320-b5764b84fe18%2Fpb9rnbb_processed.jpeg&w=3840&q=75)
