The amount of oxygen water can absorb depends upon:
temperature
pressure
salinity
all of these
The induced dipole-induced dipole interactions for ___ atoms are greater and result in a higher temperature required to boil their liquid states into a gas.
larger
smaller
the size of the atom is irrelevant
A boiling temperature in the low negative degrees of Celsius show very ___ inter-molecular interactions.
low
high
Match:
Salinity decreases the amount of hydrogen bonds to interact with dissolved gas
Hydrogen bonds are just strong dipole-dipole interactions
Coastal and island climates are mild due to the high specific heat of:
Hydrogen bonds are not only formed with oxygen
Temporary dipoles are more significant for larger atoms
The electrons in (c) atoms are less able to bunch to one side because they are confined to a smaller space, where greater electrical (d) tends to keep them evenly spread.
So it is the larger atoms, and molecules made of larger atoms, that have the strongest induced dipole-induced dipole (e) .

Where's the BOND.
Hydrogen just wants to have FON.
STOP in the name of Hydrogen.
Induced-dipole induced-dipole interactions explain why, at room temperature, natural gas (methane) is a (a) but gasoline (octane) is a (b) .
Even though their chemical composition is the (c) , the number of induced-dipole induced-dipole interactions that can take place between two methane molecules is significantly (d) than the number that can occur between two octane molecules.
The component present in the largest amount as the (a) and the other component(s) as the (b) (s).
The process of mixing a solute in a solvent is called dissolving.
To make a solution, the solute must dissolve in the solvent: that is, the solute and solvent must form a homogeneous mixture consisting of only one (c) .
Whether one material dissolves in another is a function of molecular (d) . The stronger the molecular interactions, the (e) the likelihood that the two materials will form a solution.

nitrogen
oxygen
argon
