Question

Briefly explain the following
a) The effect of cross sectional area and thermal conductivity on conduction mode
of heat transfer
b) Temperature Profile
c) Thermal conductor
d) Why the temperature of heat conduction study bench should not exceed 70°C.​

Answer 1

Answer:

x³y²z³x³y²z³x³y²z³x³y²z³

Answer 2

a. Owing to the fact that the number of collisions increases with increasing area, heat conduction depends on the cross-sectional area A. If you touch a cold wall with your palm, your hand cools faster than if you just touch it with your fingertip.

b. A temperature profile is how temperature of something changes as a function of distance. In atmospheric sciences, the temperature profile of the atmosphere is how the temperature of the atmosphere changes as a function of altitude above sea level.

c. A thermal conductor is a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself. An easy way to understand this concept is through a simple demonstration.

d. dont know
