7. Keep it for some time. Do not heat it.
8. Observe the contents in the china dish and continue observing till all the spirit evaporates

Results

Some solvents evaporate even at room temperature. The tendency of the liquid to vaporise depends on the nature of the liquid through the molecule-molecule (intermolecular) interaction in the bulk of the liquid.
