Question

To determine the coefficient of thermal conductivity of cu by Searles apparatus

Answer 1

Explanation:

K = (QL)/(AΔT)

K is the thermal conductivity in W/m.K.

Q is the amount of heat transferred through the material in Joules/second or Watts.

L is the distance between the two isothermal planes.

A is the area of the surface in square meters.

ΔT is the difference in temperature in Kelvin.
