Use the heat index table to answer the
following questions. The heat index is the
temperature it feels like, not the actual
temperature.
Relative Humidity
LESSON 29.4
Heat Index Table
Outside Temperature (°F)
75 80 85 90
70% 78 86 94 107
80% 79 87 98 114
90% 80 89 103 113
1. Find the heat index for an
outside temperature of 90°F
with a relative humidity of 70%.
2. What would be the relative
humidity if it is 85°F with a
heat index of 98°F?
3. What would the outside
temperature be when the
relative humidity is 90% with
a heat index of 80°?
4. Joe wants to take a walk. The
relative humidity is 60% and
the outside temperature is
32°C. Will it feel warmer or
cooler than the outside
temperature? Explain.
5. What generalizations can you make about the temperature that is read
on the thermometer and the heat index?
