1-How does relative humidity affect the comfort of people? Can you explain the physiological reasons for this?
2-The diurnal (daily) relationship between temperature and humidity is such that the lowest humidity should occur in the afternoon hours. It is during these times, however, when it often seems to be most humid and uncomfortable. What could be the reason for this perceived inconsistency?
3- When dew forms on outdoor objects, can it be assumed that the atmosphere is saturated? If so, why is there often no fog accompanying the dew?
4-Can you think of any agents or circumstances that may cause the mixing ratio in a room to change?
