Because viscosity refers to the degree of fluidity of a liquid, and that's something visible.It is a physical property.
physical properties of coal and snow
All material objects have physical properties.
Viscosity is the resistance for flow.Viscosity is the internal properties of fluids.Gear oil normally has larger viscosity.Kinematic viscosity is usuarally used to measure the viscosity of industrial lubricants.Dynamical viscosity (CCS) is usually used to measure low temperature viscosity for auto lubricants.Solvent or fuels has a low viscosity.Industrial oils folllow ISO viscosity classification.Auto lubes oils follow SAE viscosity classification.High viscosity usually means better protection for wear.Low viscosity usually means low friction resistance.
viscosity
Physical properties use your senses and chemical properties are when you mix two chemicals together.

It is a physical property :)
- density- viscosity- color
Earth's layers classified by their composition and their physical properties.
Ductility, conductor, viscosity, density, etc.
Examples: density, viscosity, hardness after drying, adhesivity, thermal and electrical conductivity, etc.
Many physical properties depends on temperature: density, electrical conductivity, viscosity, etc.
Examples: density, viscosity, hardness after drying, adhesivity, thermal and electrical conductivity, etc.
Im not sure about the question but i think your talking about the physical property of elemnts and molecules called viscosity. It is a measure of thickness. like honey has high a viscosity
Magma is a liquid form of rock beneath the surface of the planet. It has two properties, physical and chemical, you can notice if it is not the physical property of magma if it has the chemical properties of whatever it contains.
Lead is an element, not a property. All the elements have physical and chemical properties.
Whether it is crystalline or amorphous? Its boiling point, melting point, density, colour. Elasticity if it is a solid, viscosity if it is a fluid
