Answer:
The atoms in the cup of coffee have more energy.
Explanation:
The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.
The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.
Since the hot cup of coffee has a higher temperature, it means it also have the highest amount of energy. The correct option is;
The atoms in the cup of coffee have more energy.
<span>a homogeneous, noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension</span>
Explanation:
The metallic bonding theory basically states that valence electrons are free, delocalized, mobile, and not associated with any particular atom. It is pften regarded as a sea of electrons surrounding te atoms.
Metals are able to conduct electricity because of the free movement of the electrons (they are not bounded to a particular atom). Hence, electricity can be defined as the movement of electrons.
