While doing exercise at a temperature of T = 37∘C, an athlete loses m = 0.50 kg of water per hour by the evaporation of perspiration from her skin. Estimate the change in entropy △S of the water as it evaporates. The latent heat of evaporation of perspiration is Lv = 24.2 x 105 J/kg. Recall that evaporation is a form of vaporization that does not rely on the process of boiling

Question

While doing exercise at a temperature of T = 37∘C, an athlete loses m = 0.50 kg of water per hour by the evaporation of perspiration from her skin. Estimate the change in entropy △S of the water as it evaporates. The latent heat of evaporation of perspiration is Lv = 24.2 x 105 J/kg. Recall that evaporation is a form of vaporization that does not rely on the process of boiling at 100∘C.
