The answer is actually as temperature decreases the speed of sound decreases. "As temperature decreases, the speed of sound decreases. As pressure, or oceanic depth, increases, the speed of sound increases." - my book.
The most reactive element of this list is Chlorine, the next most reactive is bromine, and the least reactive is iodine.
All of these three elements are group 7 elements in the periodic table. It is known that the reactivity of group 7 elements decreases down the group. The most reactive element in this group is Flourine with reactivity decreasing down the group.
The reason for this decrease in reactivity is that as you go down the group, the distance between the positive nucleus that attracts valence electrons increases, decreasing the electrostatic attraction between the nucleus and the outer electrons. The other reason is that the electrons in lower energy levels closer to the nucleus repel and shield the electrons in the outermost shell or energy level of the atom.
Chlorine>Bromine>Iodine.
Biology involves living systems that interact with each other and with the environment. Like chemical processes, biological processes involve the transfer or sharing of electrons among atoms and the interaction of atoms and molecules with electromagnetic energy.
The big bang theory refers to a theoretical concept that explains the creation of our universe. It postulates that the universe started with a giant explosion that created all matter and propelled it outwards in all directions. It is the existence of cosmic background radiation that supports the big bang theory within cosmology.
