A person is in a room with air temperature of 38°C and relative air humidity of 50%. What type of heat transfer ensures maintenance of constant body core temperature under these conditions?

Answer options

1. Radiation
2. Evaporation
3. Convection
4. Conduction and convection
5. -

Explanation

Evaporation takes place at room temperature which is often well below the boiling point of the liquid. Evaporation happens from the surface of the liquid. As the temperature increases the rate of evaporation increases. Evaporation is also assisted by windy conditions which help to remove the vapor particles from the liquid so that more escape.
