164 - EASA BPL Gas Balloon Theory in English - For a fully inflated gas balloon at the same ambient pressure, envelope volume and lifting-gas temperature, what happens to lifting capacity when the outside air temperature decreases?

Question 164 - Flight Performance and Planning - BPL Gas Balloon Pilot Licence

The lifting capacity decreases because the surrounding air becomes less dense
The lifting capacity is independent of the density of the surrounding air
The lifting capacity increases because the surrounding air becomes denser
The structural maximum permitted mass automatically increases with every temperature decrease
