Volume of a peiceof grafite

Density Calculations Chemistry Tutorial

volume of substance (V) if you know its mass (m) V = m ÷ d . Check for consistency in units in your calculations: If density is given in g mL-1 then the mass must be in grams and the volume in milliltres. If density is given in g cm-3 then the mass must be in grams and the volume in cubic centimetres.

How Different Materials Affect Your Drawing Process

Known mostly as a linear medium, graphite is more flexible than many artists and teachers give it credit for. You can actually get some very fluid and painterly effects with it — for instance, by applying powdered graphite to the paper with a brush or chamois. Graphite also comes in sticks of various shapes, sizes and hardness.

Electrical resistivity and conductivity - Wikipedia

Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ ().
