The sun heats up the water causing particles to move faster and spread apart. this changes water to a gas state and becomes clouds.
The sun provides the energy needed to make water change its state in the water cycle. Solar energy drives the evaporation of water from bodies of water on Earth, converting liquid water into water vapor that eventually condenses to form clouds and precipitates back to the surface as rain or snow.
The process is called evaporation. It occurs when the sun heats the Earth's surface, causing water to change from a liquid state to a gaseous state and rise into the atmosphere as water vapor.
by boiling the water or putting it in the sun
Any change of state (solid to liquid, liquid to gas, or the reverse of these) is a physical change.You still have the stuff you started with (water to steam for example).A chemical change will result in totally different compounds (sugar burning will form carbon, carbon dioxide and water for example).
If the sun is hot enough it will turn the liquid water into vapor.
It is a physical change, because it is still H20 when it evaporates and turns into vapor.
leave it in the sun or boil it
No. The sun wont make the water make your cells to turn cancerous.
It gets warm, with heat normally made up of the sun. It moves up into clouds, condensates, and then falls as precipitation.
Obviously it is. There are no implications of a chemical change at all. It can easily be reversed, and, it's overall fundamental state remains the same.
water and sun light
Not necessarily. A temperature change can indicate a change in state, such as melting or boiling, but it could also indicate a change in the internal energy of the substance without a change in state, as in heating or cooling a solid.
