Which properties are characteristic of metalloids?

a. high electrical conductivity and a high melting point
b. low electrical conductivity and a low melting point
c. intermediate conductivity and a high melting point
d. intermediate conductivity and a low melting point

The answer is c

Explanation:

I just took the test

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
