physical because its a mixture and doesnt chemically combine
No. Making mixtures are physical changes and the chemical substances will not change.

Yes,mixing with other compounds can change the properties of a substance. The melting point, boiling point changes. Chemical properties are also can be changed.

Physical change as no new substance is formed and the properties have also not changed. Hope it helps!
