However, there are several things, such as heat, light and other forms of energy, that are not considered matter because they lack mass. The four natural states of matter are: Solids, liquids, gases and plasma. a peptide bond Triglycerides are composed of three fatty acids and one glycerol and are stable because they do not dissolve in water. D) The acceleration probably is not real, and what we attribute to acceleration is probably just a misinterpretation of the data. Because they don't reach equilibrium or a steady state, they are able to dodge the second law of thermodynamics, which states that the disorder, or entropy, of a closed system, always increases.
