Answer:
1) Capillary action
2) Cohesion
3)Miniscus
4) Adhesion
5) Viscousity
6) Surface tension
Explanation:
Intermolecular forces are forces that holds molecules together in liquid, these is possible by inter-molecular interactions that exist within the liquids.these forces includes forces such as Waals forces and hydrogen bonds.
When there is great inter-molecular forces, there will be high freezing point and boiling point . At a lower inter-molecular forces the boiling point becomes low too,which brings about great fluidity of the liquid. The liquid flow reluctantly where greater force exist in the liquid. Some of those factors used in characterizing which are;
1)adhesion,
2) surface tension,
3)capillary action,
4)cohesion,
5) meniscus,
6)viscosity.
Halogens are rarely found in native state because halogens are highly reactive.
<h3>
What is Halogens ?</h3>
The group 17 elements are known as Halogen group. These elements include Fluorine, Chlorine, Bromine, Iodine and Astatine. Halogens react with metals to form salts. Halogens are non metals. Halogens are highly reactive and halogens are never found in pure form. Halogens not occur in free state.
<h3>How many valence electron are present in Halogens ?</h3>
Halogens have seven valence electrons in the outermost shell. The electronic configuration of Halogen is ns² np⁵.
Thus from the above conclusion we can say that Halogens are rarely found in native state because halogens are highly reactive.

Answer:
Barium<Strontium<Calcium <Magnesium< Beryllium
Explanation:
Electronegativity is defined as the ability of an atom in a bond to attract the shared electrons of the bond towards itself.
Electronegativity is a periodic trend that decreases down the group and increases across the period.
Hence, if i want to arrange Beryllium, Barium, Strontium, Magnesium, Calcium in order of increasing electronegativity, i will have;
Barium<Strontium<Calcium <Magnesium< Beryllium
Answer: A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it.
The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions.
Water has a high boiling point because of the strong hydrogen bonds between the water molecules; it is both a strong hydrogen bond donor and acceptor.
The first change of phase is melting, during which the temperature stays the same while water melts. The second change of phase is boiling, as the temperature stays the same during the transition to gas
