the bright cloud of gas that surrounds their nuclei as they approach the sun makes the surface difficult to determine.
it is composed of ice and dust
yes they are one of the 7 physical properties===========================Would they not be 2 of the 7 ?

The chemical symbol of carbon is C. Two physical properties are (1) solid at room temperature and (2) high melting point.

The physical properties of a textbook are **************************
The physical properties of the things in the mixture. It could be that one part of the mixture is soluble, the other part insoluble - both physical properties. It could be that you use the boiling point of 2 liquids to separate them - physical properties. You could use a magnet if one part is magnetic and the other isn't - physical properties. And so on. But you are relying on physical properties rather than chemical properties.
