Using the second latent heat equation C2 - C1 = dLdT - LT, under which condition will the specific heat of saturated vapor (C2) be negative for water at 100°C (T = 373 K), given C1 = 1 cal/g·K and L is the latent heat?
- 1If L = 800 - 0.705T✓
- 2If L = 800T - 0.0705
- 3If L = 800T2 - 0.705T
- 4If L = 800T - 0.705T2
Correct answer
If L = 800 - 0.705T
