Match the definitions here with the physical properties they represent. Density
Freezing point
Boiling point
Magnetism
Mass
Volume
Conductivity
Solubility

The ability to dissolve in a substance
The ability to transport heat and electricity
The mass of an object divided by its volume
The temperature at which something freezes
The temperature at which something boils
The ability to attract iron
The space something occupies

Density - The mass of an object divided by its volume

Freezing point - The temperature at which something freezes

Boiling point - The temperature at which something boils

Magnetism - The ability to attract iron

Mass

Volume - The space something occupies

Conductivity - The ability to transport heat and electricity

Solubility -  The ability to dissolve in a substance

Explanation:

You gave 8 physical properties but only 7 definitions, so I left one physical property blank.

Hope this helps!

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
