Find entropy change from heat and temperature.

Entropy change (ΔS) (J/K) 6.711

Formula: ΔS = Q ÷ T (reversible)

Step-by-step with your numbers:

1. Values used:

2. Heat transferred (Q) = 2,000 J

3. Temperature = 298 K

5. Entropy change (ΔS) = Heat transferred (Q) / Temperature = 2,000 / 298 = 6.711J/K

Did we solve your problem today?

Entropy change for a reversible heat transfer at constant temperature.

The math behind it

ΔS = Q ÷ T (T in kelvin). Heat into a system increases its entropy.

2,000 J at 298 K → 6.71 J/K.
