A uniform cylinder of length L and thermal conductivity k is placed on a metal plate of the same area S of mass m and infinite conductivity. The specific heat of the plate is c. The top of the cylinder is maintained at T 0 . Find the time required for the temperature of the plate to rise from T 1 to T 2 (T 1 < T 2 < T 0 ).
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
The whole metal plate will always be at uniform temperature (T) since it has infinite conductivity.
⇒ – mc 
= 
= 
⇒ t =
