globules of mercury kept in a petri dish which on shaking come together to from one big globule. give reason
Answers
The globules of mercury kept in a petri dish upon shaking come together to form one big globule because of the strong cohesive forces between the mercury atoms.
- The atoms of mercury have very strong cohesive forces between them.
- When the small globules of mercury come in proximity to one another, these cohesive forces come into play.
- They cause the small globules of mercury to combine together.
- Hence, a big globule of mercury is formed.
Chemical attraction or affinity
Explanation:
The globules of mercury kept in a petri dish which on shaking come together to from one big globule due to the chemical attraction between the atoms of mercury. There exists a strong chemical attraction between the mercury atoms that causes them to have a strong pull when they come closer to each other, thus causing them to overcome the attraction of other surface it is sticking to or gravity and stick to each other. Thus forming a bigger globule of mercury.
