Question

As water changes state with water management, which of these changes of state involve verbs or actions?

1) Evaporation
2) Condensation
3) Melting
4) Boiling

Answer 1

The changes of state involving water that are actions or verbs are evaporation, condensation, melting, and boiling, all of which are physical and reversible processes.

Step-by-step explanation:

Changes of State involving Water

When water changes state with water management, the processes that involve actions or verbs are:

1. Evaporation is the change from a liquid to a gas below its boiling point, due to liquid molecules escaping into the gas phase. This can occur, for example, when a puddle of water disappears as it warms up by the sun.
2. Condensation is the transition of water vapor to the liquid state. This happens when water vapor molecules in the air cool and change back into liquid form, often visible on surfaces like cold glasses or windows.
3. Melting occurs when a solid turns into a liquid; this is seen when ice becomes water as it warms above freezing temperature.
4. Boiling is the rapid vaporization of a liquid at its boiling point, such as when water in a pot turns to steam as it's heated on the stove.

Each of these is an example of a physical change, which is a reversible transition involving a change of state. These changes are integral parts of the water cycle and are critical to many natural and technological processes.
