Gas is NOT a property but matter.
As such it has both
and
Each atom and molecule will have its own magnetic moment - thus making it an intensive property. If you get a collection of such atoms or molecules in a gas, the total combined magnetic moments will be an extensive property.
Ammonia is a gas at room temperature and is considered an intensive property because it does not depend on the amount of ammonia present in the system.
Why malleability are intensive property
The melting point is an intensive property.
It is a physical property. boiling is just evaporation and all it is is a change in matter from a solid to a gas, therefore being considered a physical change rather than chemical.
Malleability is an intensive property.

Molarity is an intensive property.
intensive property
An intensive property is one that does not depend on the amount of substance present. So, compressibility would be an INTENSIVE property.
Malleability is typically considered an intensive property because it does not depend on the amount of substance present. It describes the ability of a material to be hammered or rolled into thin sheets without breaking.
Surface tension is an intensive property, which means it does not depend on the amount of substance present and remains constant regardless of the size of the system.
