Yes, this is a physical change.
No, the process of evaporating water from seawater is a physical change, not a physical property. Physical properties are characteristics of a substance that can be observed without changing the substance itself, whereas physical changes involve a change in the state or appearance of a substance without altering its chemical composition.
Yes, it is.
Water evaporating from a puddle is an example of a physical change, specifically the transformation of liquid water into water vapor. This process involves a change in state from liquid to gas without altering the chemical composition of the water molecules.
Water evaporating, crumpling or cutting paper, and inflating or deflating anything are all physical changes. Also water turning into ice is one.
It is a simple evaporation.
Evaporating and condensing.
It is a physical change as it can be "undone" by evaporating the water. An simple example of a chemical change is baking a cake, you can't un-bake a cake. To work out whether it is a chemical or physical change just think whether it can be undone or not.
An example of oxidation would be paper burning because it involves a chemical reaction where paper combines with oxygen in the air to produce heat and light. Water evaporating and sugar melting are physical changes, not chemical reactions involving oxidation.

An example of an endothermic process is evaporating. Evaporation requires an input of energy to convert liquid water into water vapor, so it is an endothermic process.
Salt makes up approximately 3.5% of seawater.
