Tot Otto is evaluating properties of different metals in order to determine which ones are the best to use for building and wiring his house. He created the table below:
Material
Appearance
Reactive to Water
Flammable Conductive Ductible
No
No
Excellent
Yes
Material 1 Reddish soft metal
Material 2
Shiny, sont
Very violent
Extremely
Excellent
Yes
Material 3
Soft
Yes
Yes
Yes
Yes
Material 4
Shiny, hard
Creates rust in moist air
No
Yes
Yes
Materials
Liquid, shiny
No
No
Yes
Yes
Select the conclusions that Otto can make based on his information in the table. .
Select the objects by clicking on the tile. Clicking on a selected object will deselect it.
Metal 2 would not be very good in building due to its chemical properties.
Metal 1 would be excellent house wiring due to its physical properties
Metal 5 would be good for building a house because it is conductive and ductile.
Metal 4 could be good for home building except for its physical properties
Metals 1 and 4 have the best chemical properties for home buding of the
Metal 3 would be excellent for homebuilding based on its chemical properties
