A paddle wheel is connected with a block of mass 10 kg as shown in figure. The wheel is completely immersed in liquid of heat capacity 4000 J/K. The container is adiabatic. For the time interval in which block goes down 1 m slowly calculate
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
W = mgh = 10 × 10 × 1 = 100 J
No heat supplied from out side
100 = 4000 Δθ
Δθ = 
ºC
