Hi there!
We can use the following equation for constant velocity:
d = displacement (m)
v = velocity (m/s)
t = time (s)
Plug in the givens:
Given:
= 323 K
= 293 K
specific heat of aluminium,
specific heat of water,
Formula Used:
Q = m
Solution:
Let the temperature at equilibrium be ' ' K
Now at equilibrium, using the given formula:
Temperature at equilibrium, = 295.513 K
Now, change in entropy(in J/K) is given by:
Q = m
= 12094.28 cal
Now,
= 40.93 cal/K = 9.78 J/K
Therefore change in entropy is given by:
