Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
The chemical name for the color purple is Manganese violet, which is a synthetic pigment used in various applications such as inks, paints, and plastics to achieve a purple hue.
I would say Potassium is the closest chemical to a purple as it is a lilac/purplish colour.
Yes.
The reaction between glycine and ninhydrin solution results in the formation of a purple compound called Ruhemann's purple. The chemical equation for this reaction is: 2 Glycine + Ninhydrin --> Ruhemann's purple. The exact chemical structure of Ruhemann's purple is not fully understood, but it is commonly used in the detection of amino acids.
Lithium and strontium have a red flame.
You can't, have to see it to know it is purple!
No, strontium and iodine have different properties. Strontium is a soft, silver-white metal that is reactive with water, while iodine is a nonmetallic element that is a dark purple solid at room temperature and forms diatomic molecules. Their chemical properties and reactivity are quite distinct.

No, the color purple is a physical property of an object that results from the absorption and reflection of certain wavelengths of light. It is not the result of a physical or chemical change, but rather the interaction of light with the object's molecules.
Space is defined by its dimensions, properties, and contents. If its contents or properties (or even its dimensions) produce a purple colour on the application of light, either by scattering of red and blue frequencies, or by absorption of green, it could be considered 'purple space'. A room with purple wallpaper, for instance, is a space that is purple. Is the vacuum of outer space purple? Not really- it lacks colour generally until you shove something purple into it and shine a light upon it consisting of the requisite frequencies, or something white with purple light... or unless you can manipulate its properties to influence the frequency/absorption of light passing through it... or unless it has purple curtains...
Yes, iodine becoming a purple gas is a physical change, not a chemical change. A chemical change involves the formation of new substances with different chemical properties, whereas in this case, the iodine is just changing its physical state from solid to gas without forming any new substances.
Navy is used to describe a shade of dark blue (not purple), because of the color used in certain navies' dark-blue-and-white uniforms.
