Answer:
Heat, once absorbed as energy, contributes to the overall internal energy of the object. One form of this internal energy is kinetic energy; the particles begin to move faster, resulting in a greater kinetic energy. This more vigorous motion of particles is reflected by a temperature increase.
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances.
Answer:
Homogeneous: 1 phase, heterogeneous 2 or + phases
Explanation:
Homogeneous mixture: water + vinegar
water + ethyl alcohol
Heterogeneous mixture: water + oil.
<span> </span><span><span>Colored ions indicate the presence of a transition metal.
Transition metals display colors because of their incompletely filled d
orbitals. As the transition metal absorbs a particular wavelength of
light to raise the electron orbital, it causes the light that passes
through the solution to emit a color.</span></span>
I found this on google
“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”
I hope this helps
