Water is constantly being recycled on Earth through the hydrological cycle, so there is no "new" water being formed every day. Most of the water on Earth has been here since the planet was formed.
The molecules in water are not tightly packed as such flow and spread very easily but when the water turns to ice the molecules in the liquid enlarge ans they tightly packed and thus, when water turns to ice new molecules are not formed.
No, new substances are not formed in a physical change. A physical change is a change in the form or appearance of a substance without changing its chemical composition.
If a solution is formed after the water evaporation the initial solid is obtained.
There is no new product being formed, eg. its just sugar plus water. It's not like a new substance is being formed. For example a chemical change could be Iron and oxygen, which forms something new, which is Iron Oxide. Get it?? :)
A new substance formed by a reaction is called a product. During a chemical reaction, reactants undergo a transformation, resulting in the creation of products with different properties. For example, when hydrogen gas reacts with oxygen gas, water is formed as a new substance. This process illustrates how chemical bonds are broken and reformed, leading to the generation of new materials.
Because the water cycle produces new water everyday.

When you say that there is moisture in the air it pretty much means water in the air.It is a physical change, as no new products have been formed.
washing soda
Physical change. Example: ice melting into water. They're both H2O, so chemically speaking, no new substance is formed.
faris jibril cries too much everyday
Water everyday if it has not been watered naturally and cut everyday - if possible.
It depends upon nature of substances for example when Glucose or Salt are dissolved in water no new substance is formed so these are physical changes but when Ammonia gas is dissolved in water Ammonium and hydroxide ions are formed so it is a chemical change.
because it is reversible and no new substances are formed
