Why does a sky lantern rise? It’s not just “hot air.” This comic shows the exam‑ready scoring chain:
Air inside lantern has high temperature.
Density of air decreases → low density air.
Upthrust (buoyant force) is produced.
Upthrust becomes greater than weight.
Lantern rises into the sky.
The exam trap: don’t stop at “hot air makes it rise.” You must explain the density change and the force comparison.
AHA! Not just hot air — it’s upthrust victory. Not by sight, but by INSIGHT!
