Water (0.12m) COPPER A 50-kg copper block initially at 80°C is dropped into an insulated tank that contains 0.120 m3 of water at 25°C. Determine the final equilibrium temperature and the total entropy change for this process. Properties: Take the density and specific heat of water as p-997 kg/m3 and cp-4.1SKJ/kgK, respectively, and the specific heat of copper as cp=0.386kJ/kgK (values at room temperature).

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
