Answer:
The formation of clouds is a physical change because there is a phase transformation cycle of natural water from liquid to gas and then, gas to liquid.
Answer:
ExplanatiCloud formation is a physical change rather than a chemical change.
In the atmosphere, clouds are formed when water vapor condenses into tiny water droplets or ice crystals. This process occurs due to changes in temperature, pressure, and the presence of condensation nuclei (such as dust particles or pollutants).
During cloud formation, no new substances are formed, and no chemical reactions occur. The water molecules in the air simply undergo a phase change from a gas (water vapor) to a liquid (water droplets) or a solid (ice crystals). This change in the physical state of water is reversible, meaning the cloud can evaporate and return to a gaseous state under different conditions.
Chemical changes, on the other hand, involve the formation or breaking of chemical bonds, resulting in the creation of new substances with different chemical properties. Examples of chemical changes include combustion, rusting, and digestion.
Therefore, cloud formation is considered a physical change because it involves a change in the physical state of water vapor without any alteration of the chemical composition or identity of the water molecules themselves.on:
