THE HUMMER
ACTIVITIES Nº5.
1. Complete the table of the Density of these materials:
ACTIVITIES Nº6:
1.Explain what is meant by the term alloy?
An alloy is a mixture of two or more metals which is produced when a material that requires certain properties and it doesn't exist is needed
2.Explain in detail the difference between ferrous and non-ferrous metals.
Ferrous: they own a characteristic bright, are good heat and electricity conductors, are malleable and ductils, almost all of them are solid and have high melting point
Non ferrous: they don't have any bright, can be solids, liquids or gases, are bad heat and electricity conductors, are very fragiles and they have loww melting and boiling points.
3.Define the terms ductile, malleable and corrosion resistant.
Ductile: it's when a metal deforms, usually by stretching along its length.The length that a material can be stretched without breaking.
Malleable: when a metal is malleable it indicates the amount of hammering, pressing and shaping a material can take without breaking.
Corrosion resistant: when a metal is protected or avoid corrosion
