Transmission Of Heat Question 46
Question: The temperature gradient in a rod of 0.5 m long is $ 80^{o}C/m $ . If the temperature of hotter end of the rod is$ 30^{o}C $ , then the temperature of the cooler end is
Options:
A) $ 40^{o}C $
B) $ -10^{o}C $
C) $ 10^{o}C $
D) $ 0^{o}C $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \frac{{\theta _{1}}-{\theta _{2}}}{l}=80\Rightarrow \frac{30-{\theta _{2}}}{0.5}=80\Rightarrow {\theta _{2}}=-10^{o}C $
