A metallic cylindrical vessel whose inner and outer radii are r 1 and r 2 is filled with ice at 0ºC. The mass of the ice in the cylinder is m. Circular portions of the cylinder is sealed with completely adiabatic walls. The vessel is kept in air. Temperature of the air is 50ºC. Find time elapsed for the ice to melt completely. (Thermal conductivity of the cylinder is k, its length is λ . Latent heat of fusion is L).
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
For the cylinder R = 
mL = 
. time
⇒ Where L = latent heat of fusion
⇒ Time = 
=
