hardness
Whether a substance will float or sink in another substance.
thermal conductivity
Not exactly. It is more like a property that expresses the RELATIONSHIP between two different materials. For example, wood on wood can have one coefficient of friction, wood on glass another, and wood on concrete yet another, so this isn't something that can be attributed to a single material (in this case wood).
That is a physical change because it has not had an explosive or bubbly substance.

Hardness
It is a change of a physical property - for example the variation of temperature.
Chemical property.
The Mohs Scale of Hardness measures how well a substance resists scratching by another material.
solids
Magnetism is a physical property that is mediated by magnetic fields.The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
physical
Its a chemical property because the substance has changed into another

Colourless is a property, or word to describe matter, however the "gas" would be something you're describing. However, if a reaction is omitting a colourless gas, it could be considered a physical property of the reaction.
