Question

One end of a 2.5 m long metal bar is in steam and the other is in contact with
ice. If 12g of ice melts per minute. What is the thermal conductivity of the
metal? Given cross-section of bar = 5 x 104m? and latent heat of ice is 80cal/g.​

Answer 1

Answer:

K=800 in SI units

Explanation:

Heat (H) lost to ice is heat gained

H=(Δm)L =KA$\frac{dT}{dx}$

(12/60)(80)=K(5x$10^{-4}$)$\frac{(100-0)}{2.5}$

16=K(0.02)

K=800 in SI units
