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.

A 0.1 kg block of pure copper at a temperature of 250°C is dropped into a 4°C water bath. The bath contains 0.03 m^3 of water and is well insulated. Find the final temperature after the block and the water reach thermal equilibrium. (It is reasonable to assume the following: the specific heat of water is equal to the value at 4°C; the specific heat of the material in the block can be taken to be a constant value evaluated at a temperature mid-way between the initial temperatures of the block and the water.)
