Question

The temp of hot and cold end of a 20 cm long rod in thermal steaddy state are at 100c and 20c temperature at the centre of the rod

Answer 1

Answer:

The Correct Answer is 60 Degree Celcius

Explanation:

A temperature gradient is a physical quantity that specifies how quickly and in which direction the temperature changes around a specific area. The temperature gradient is a three-dimensional quantity that is measured in degrees per unit length. The SI unit for temperature is kelvin per metre.

Temperature Gradient = $\frac{100 - 20}{20}$ = 40 C/cm

Temperature at Center = 100 - (4 X 10) = 60 Degree Celcius
