Which states are recognized for water in various physical forms?

1. Solid, liquid and gas

2. Ice, vapor, and dew

3. Liquid, solid, and steam

4. Water, ice, and mist

The correct answer is: Solid, liquid and gas

The recognition of water in various physical forms is based on its ability to exist in three primary states: solid, liquid, and gas. This fundamental classification reflects the physical properties of water and its behavior under different temperature and pressure conditions. In its solid state, water exists as ice, being less dense than its liquid form. The liquid state is what we typically think of as water, existing at temperatures above freezing. In its gaseous state, water becomes water vapor or steam, which occurs when liquid water is heated to the point of evaporation. This understanding aligns with the basic principles of chemistry and physics regarding water’s phase transitions. The other options refer to specific manifestations or states of water but do not encompass the complete classification of its physical forms as accurately as the solid, liquid, and gas designation does. This broader terminology is pivotal in scientific discussions and applications involving water in its various states.
