Question

5. A very large hot air balloon and its accompanying
structure (i.e. the basket, rigging, equipment, etc) have
a mass of 400 kg. The air inside the balloon must be
heated to a temperature of 200 OC for the balloon to lift
off the ground when the outside air temperature is
16.0OC. To what temperature must the air be heated if
the balloon is to lift off with three 80.0-kg people
aboard?
Note: Problem 5 requires three pictures of the balloon
(cold, hot, hotter), with the appropriate information
labeled in each picture. Label them 1 2 3. Label the pressure, volume, density and
temperature of the air in each of the balloons.

The only thing I need are the pictures. I can do the calculations myself. I'm just a little confused about what they were asking regarding the three pictures.
