The inner surface of a 5 cm diameter, 3 mm thick, and 7 cm high
styrofoam cup is at 70 °C. the outer surface is exposed to air at
20 °C. the surface heat transfer coefficient associated with the
outer surface is 8 w/m2 °C. Determine
The heat transfer rate through the cylindrical surface of the
cup.
The outer surface temperature of the cup.

Compare (take the ratio) the rate of heat conduction through a
20.0-cm-thick wall that has an area of 10.0 m2 and a thermal
conductivity twice that of glass wool with the rate of heat
conduction through a 0.750-cm-thick window that has an area of 2.00
m2, assuming the same temperature difference across each. Show a
few steps. Qualitatively, explain how you can reduce heat
conduction through a window in winter.

In the Musculoskeletal System and Connective Tissue chapter of
ICD-10-CM, what is the difference between a pathological fracture
and a traumatic fracture? Give an example of a scenario for coding
a pathological fracture. Along with your example, provide the
ICD-10-CM code(s) that would be assigned for the scenario. Be sure
to follow coding guidelines and instructional notes, and assign the
appropriate 7th character if needed.
