What will be observed after a few minutes, and why?
- Both jars become evenly brown because bromine gas diffuses into the empty jar.
- Only the lower jar is brown because bromine particles are too heavy to move up.
- The upper jar becomes colourless because bromine sinks into the lower jar.
- Only the upper jar is brown because air pushes all bromine upwards.
