The latent heat of vaporization of H2O at body temperature (37.0∘C) is 2.45E+6 J/kg. To cool the body of a 71.0 kg jogger [average specific heat capacity = 3470 J/(kg*∘C)] by 1.70∘C, how many kilograms of water in the form of sweat have to be evaporated?
The latent heat of vaporization of H2O at body temperature (37.0° C) is 2.42 106 J/kg. To cool the body of a 84 kg jogger (average specific heat capacity = 3500 J/ (kg · C°)) by 1.2° C, how many kilograms of water in the form of sweat have to be evaporated? There are 2 steps to solve this one.
The latent heat of vaporization of water is 2.26 106 J/kg and its specific heat is is 4190 J/(kg?K). If you add 700 kJ of heat to 700 g of water at 70.0 C, how much water is left in the container?
Question: Latent Heat of Vaporization of Liquid Nitrogen Introduction When heat is transferred to or from substance its temperature usually increases or decreases unless that substance is undergoing a change of phase (e.g., a solid is changed into a liquid phase or a liquid state is changed into its vapor phase).
Step 1. Latent heat is the specific enthalpy difference between two phases of a substance at the same temperature. The latent heat of vaporization ( H V AP ) is the water vapor specific enthalpy minus the liquid water specific enthalpy. Heats exist for each of the six processes by which matter changes between the three terrestrial states of matter.
