Answer: In metals, some of the electrons (often one per atom) are not stuck to individual atoms but flow freely among the atoms. ... Those are the same factors that determine how well the metal conducts electricity. Therefore the more electricity an object can conduct the better it can conduct heat.
The answer is false, if thats what youre asking.
Answer:
The rate of transfer of heat is 0.119 W
Solution:
As per the question:
Diameter of the fin, D = 0.5 cm = 0.005 m
Length of the fin, l =30 cm = 0.3 m
Base temperature,
Air temperature,
k = 388 W/mK
h =
Now,
Perimeter of the fin, p =
Cross-sectional area of the fin, A =
A =
To calculate the heat transfer rate:
where
Now,
Sound waves can't travel through a vacuum.
