Work (isothermal)
W = nRT ln(V₂/V₁)
Where: R = range / radius / resistance, T = time period (s) / temperature (K) / tension (N), V₁ = V₁, V₂ = V₂, W = work (J) / weight (N), n = number (n)
Solved example
Given: R = 7, T = 5, V_1 = 10, V_2 = 4, n = 3
Find: W (work (J) / weight (N))
- Formula: W = R·T·n·ln(V₂/V₁)
- Substitute the values: W = 3·5·7·ln(4/10)
- Result: W = -96.210527 J
Answer: W = -96.210527 J
