Question

what happens if mercury falls on our hands
clothes
and books

Answer 1

Mercury is cohesive in nature. Therefore, if it falls on our hands, books or clothes it will form tiny droplets unlike water which spreads throughout the surface due to its adhesive nature.Intake of mercury is harmful and fatal but contact with the skin doesn't cause any harm but it should be cleaned properly in order to avoid its intake by mistake or accidentally,etc.
