Heat Index
The heat index is the temperature that your body feels, not the air
temperature that the thermometer measures. The relative humidity
combines with the air temperature to create the heat index. For more
information on this, click here.

If the relative humidity is 35 percent, how much will the heat index increase if the temperature rises from 70 to 85 degrees during the day?
If the relative humidity is 25 percent and the temperature is 80 degrees in the morning, and the afternoon yields relative humidity of 15 percent and temperature of 105 degrees, what was the heat index in the morning and afternoon?
If the radio station broadcasted a heat index of 115, and you checked your thermometer reading of 100 degrees, what is the relative humidity?
If the relative humidity is at 95%, how high can the temperature get?
