1. On a clear and calm day, the air temperature at sunrise is 5 °C (41 °F) with a relativehumidity of 90%. The air temperature reaches a maximum of 15 °C (59 °F) at 3 p.m.Assuming that no water vapor is added to or removed from the air, predict the value of therelative humidity at 3 p.m.
2. If the relative humidity is 68% and the vapor pressure is 16 mb, what is the approximate saturation air temperature?
3. Outdoors, the air temperature is 5 °C (44 °F) and the relative humidity is 70%. What is the relative humidity of the air if it is drawn indoors and heated to 20 °C (68 °F)? Assume thatno water vapor is added to or removed from the air. (This is the situation with heating homesin the winter season.)
