Solution:
Concept- Physical state of matter is the form substance in visibility.The three main states of matter are solid, liquid and gas. They differ in their interatomic attraction.
Solids are substances like stone, powder etc in which atoms are closely packed. Solid is symbolized by the letter, s in parenthesis.
Liquids have the property to flow. The atomic interactions are less than solid but more than gas. It is represented as ‘l’ in brackets.
Gases have the highest interatomic distance. They are represented as ‘g’ in brackets.
The term ‘(aq)’ represents, a substance dissolved in water. Even though it’s called an aqueous state, its physical state is actually liquid.
The correct symbols for physical states are-
Solid, (s)
Liquid, (l)
Gas, (g)
Hence, the correct answers are options 2 and 3.
