Is the static coefficient of friction between two surfaces a

Is the static coefficient of friction between two surfaces an extensive or intensive property? Explain why. Is the hardness of 1040 steel an extensive or intensive property? Explain why.

Solution

Coefficient of friction is same for same materials are contact even if you change remaining parameters except material

So it is intensive property

Hardness of any material don\'t change with the size of sample

So it is also intensive property
