What is two physical properties of pencil lead?
Two physical properties of pencil lead are its hardness, which is measured on the Mohs scale, and its color, typically ranging from dark grey to black.
What are two physical properties of a pencil lead?
Two physical properties of pencil lead are its hardness, measured using the Mohs scale, and its color, typically either graphite gray or black.
Physical properties of boron?
Boron is a solid metalloid element with unique physical properties. It is hard and brittle with a blackish-brown color. Boron has a high melting point and is a poor conductor of electricity at room temperature.
What are the physical properties of boron?
== == Some physical properties of boron are as follows: - rough in texture - black, white, or gray for the color - has a small shine or luster
Physical properties of coal and snow?
Coal is a black, carbon-rich sedimentary rock that is combustible and used as a fuel source. It is hard, brittle, and has a black or dark brown appearance. Snow is a precipitation in the form of ice crystals that fall from clouds. It is white, soft, and composed of frozen water molecules. Snow is light and can vary in density depending on the temperature and moisture content.
What are the physical properties of carbon?
The most common properties are, black solid (except diamond), insoluble in water, combustible.

What are the physical properties of black?
Black is the absence of color and light, resulting in a lack of reflectivity. It absorbs most wavelengths of light, giving it a characteristic dark appearance.
What are some of the physical and chemical properties of a pencil?
A pencil is typically made of graphite and clay mixed with a binding agent. Its physical properties include being solid, cylindrical, and having a smooth surface. Chemically, graphite is a soft, black, opaque form of carbon that leaves a mark on paper due to its lubricating properties.
What is the freezing point of biotite?
Biotites comprise a range of different black mica minerals with different chemical composition and physical properties.
