Medium

(Originais Teachy 2023) - Question Medium of Physics

The concept of Entropy, created by Rudolf Clausius, is used to quantify the degree of disorganization of a thermodynamic process. For a dynamic process, this quantity depends on the variables temperature, volume, and pressure, related by the equation PV=nRT. Which of the following items best represents the Entropy of a system?
a.
The variation of enthalpy of the system
b.
The amount of substance involved in the system
c.
The internal energy of the system
d.
The temperature of the system
e.
The disorganization of the system

An experiment was conducted in a laboratory in which two blocks of 1 kg of ice and water, each with different temperatures, are placed in a thermally insulated container. Initially, the ice block is at -20¬įC and the water, in liquid state, is at 100¬įC. After some time, we observe that the temperature of the blocks stabilizes at 0¬įC and the initial ice block completely melts. Knowing that the specific heat of water is 4186 J/(kg¬∑K) and the specific heat of ice is 2090 J/(kg¬∑K), the enthalpy of fusion of ice is 333 kJ/kg and that water is incompressible: a) Calculate the amount of heat exchanged between the ice block and the liquid water for the ice to completely melt and the temperature of the blocks to be in equilibrium. b) Determine the entropy change for each block during the process. c) Considering the system formed by the two blocks and respecting the second law of thermodynamics, verify if the total entropy of the system increased, decreased, or remained constant.

One of the main principles of Thermodynamics states that all natural processes tend towards the highest possible Entropy, that is, towards the highest possible disorder. This means that the particles present in the system tend to disperse and create a state of thermodynamic equilibrium. This principle can also be called:
