Answer 2

Answer:

The temperature difference between the two ends of the rod will be 4°C.

Explanation:

Given:

Length of the metal rod = 0.4m

The temperature gradient in the rod = 10°C/m

To find:

The temperature difference between its two ends.

Solution:

We know that the temperature gradient resembles the change in temperature of a material per unit of its length. Hence to find the temperature between the two ends of the metal rod we can multiply its temperature gradient with its length.

Hence, in this case, the temperature difference between the two ends of the metal rod = 0.4× 10 = 4°C

Thus the temperature difference between the two ends of the rod will be 4°C.
