Answer:
Exposure of silver chloride to sunlight for a long duration turns grey due to photolytic decomposition i.e decomposition in the presence of sunlight.
Explanation:
When silver chloride, AgCl is exposed to sunlight for a long time, it will undergo decomposition as the sunlight provides sufficient energy needed to decomposed the salt, AgCl to metallic silver and chlorine gas. This can be seen in the equation below:
2AgCl —> 2Ag + Cl2
Liquid makes up most of the body
A solid is hard and the molecules are packed together, a liquid can move around freely because the molecules aren't as packed together :)
Being frozen, staying a liquid, becoming ice, and becoming a gas (steam)
The answer is B. Below freezing
