Question

Constant Value of Thermal Conductivity
The temperature distribution for a plane wall for steady state heat flow and constant value of thermal conductivity is: 1) Logarithmic 2) Parabolic 3) Linear 4) All of these

Answer 1

The temperature distribution for a plane wall for steady state heat flow and constant value of thermal conductivity is Linear.

Answer 2

The correct answer is option (3) Linear.

Explanation:

• The temperature distribution for a plane wall for steady state heat flow and constant value of thermal conductivity is Linear.
• According to Merriam-Webster, thermal expansion is the increase in linear dimensions of a solid or in the volume of a fluid because of change in temperature.
• Therefore, it is the change in the dimensional properties of an object when exposed to changes in temperature.
• Thermal conductivity increased linearly with an increase in temperature.
