Question

If a copper metal of diameter 5cm and length 1m is stuck into the base of a hot water bath such that the heat of the water at 80° Celsius is transmitted to the other end. calculate :

(1) the temperature gradient
(2) the quantity of heat supplied ( Take thermal conductivity of aluminium to be 386W/mk), if the temperature at the other end is 30° Celsius ​

Answer 1

Answer: The temperature gradient:

Explanation: ∇=T/L=80/1=80°C/m.
