Guida verificata passo dopo passo1
Recall the physical properties of mercury at room temperature: mercury is a metal that is liquid under standard conditions.
Consider the appearance of mercury: it is known for its silvery color and shiny, reflective surface, unlike most liquids which are transparent or colored.
Think about the shape mercury takes when in small amounts: due to its high surface tension, mercury forms nearly spherical droplets rather than spreading out flat.
Compare the options given with these known properties: mercury is not yellow, viscous, sticky, nor is it solid and brittle at room temperature.
Conclude that the description 'a silvery, highly reflective, and spherical liquid' best matches the known characteristics of a drop of liquid mercury.
