Conduction can occur within a single substance, but parts of the substance must have which property?
a. different temperatures
b.) different textures
c.) different particle sizes
d.) different colors

Yes, heat can flow between different parts of the same substance, whether it's solid, liquid, or gas, but that only happens when the parts have different temperatures. (A)

  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
