Question

What does delta S mean in thermodynamics?

Answer 1

1. In any thermodynamic system if we observe any randomness of the particle then the term is said as entropy.
2. Entropy is the thermodynamic quantity that tells us the degree of a disordered particle in any system.
3. It is a more convenient way to determine the change in entropy compared to the actual entropy.
4. Change in entropy is measured by the change in state.
5. In a system if the final entropy is higher as compared to the initial then the change in entropy is taken as positive.
6. Mathematically entropy is represented as follows:$∆\mathrm{S}={\left(\frac{∆\mathrm{Q}}{\mathrm{T}}\right)}_{\mathrm{rev}}$
7. Where a change in heat is denoted by$∆\mathrm{Q}$, the absolute temperature is T, $∆\mathrm{S}$ is a change in entropy.
