The diameter of metal wire is often referred to by its american wire-gauge number. a 16 gauge-wire has a diameter of 0.05082 in. what length of wire, in meters, is found in a 1.00 lb spool of 16-gauge copper wire? the density of copper is 8.92 g/cm3.

length of wire = 38.82 m

Explanation:

∴ 16 gauge ≡ 0.05082 in * ( 2.54 cm/in ) = 0.12908 cm

∴ m spool = 1 Lb = 453.592 g

∴ ρ = 8.92 g/cm³

cross section area:

⇒ A = π*D²/4 = π*(0.12908)²/4 = 0.0131 cm²

⇒ L = ((453.592 g) *(cm³/8.92 g)) / ( 0.0131 cm² )

⇒ L = 3881.765 cm * ( m/100cm) = 38.82 m

1. they vary with a higher number because boiling is way hotter than melting
