Judging from its unit W/m·K, can we define thermal conductivity of a material as the rate of heat transfer through the material per unit thickness per unit temperature difference? Explain.
Problem begins here:
An object at an unknown temperature is placed in a room which is held at a constant temperature of 30 F. If after 10 minutes the
temperature of the object is 0 F and after 20 minutes the temperature of the body is 15 F what is the initial temperature of the
object? Assume Newton's Law of Cooling which states that the rate of change of the temperature of a body is proportional to the
temperature difference between the body and its surrounding medium.
Choose the correct answer from among the given choices.
-55 F
-30 F
(c) -14 F
D) -12 F
O F
(F) 45 F
G) 68 F
The problem is unsolvable as it lacks additional information.
