Respuesta :
A thermodynamic process occurs in which the entropy of a system changes by −8 j/k and according to the second law of thermodynamics, the change in entropy must be equal to +8 j/k .
Why is there a change in entropy ?
According to second law of thermodynamics:
Entropy change of system = − Entropy change of environment
∴ ΔS [tex]sys[/tex] = - ΔS [tex]env[/tex]
∴ ΔS [tex]sys[/tex] = - (- 8 j/k)
∴ ΔS [tex]sys[/tex] = +8 j/k
Hence , the entropy change is equal to +8 j/k .
What is entropy change?
- The degree of chaos present in a material, system, or universe is known as entropy.
- For gases, we can say that it is their energy, as the molecules move in all directions the more energetic they are.
- Entropy increases with temperature since it is inversely correlated with both.
- The entropy of each system varies as heat is transferred across boundaries separating a system from its environment or between two systems or entities.
- When heat is given off or released, entropy decreases.
