A bond between two atoms is polar if the electrons of the bond are unevenly distributed. If the bond is polar enough the possibility exists for one atom to take both electrons. If it does that the bond breaks and it is said to have 'dissociated'. In general, solvents are referred to as polar and non-polar. Water (H2O) is a polar solvent while Acetone (Propanone) is a non-polar solvent. Water will dissolve ionic species such as salts, while Acetone will dissolve covalent (non-ionising) compounds.

How do molecules behave in each of the states of matter?
Solids - Bonds between molecules are strong, holding a constant form with a definite mass. Liquids - Bonds between molecules are not as strong, still have a definite mass due to their temperature and take the form of the container. Gases - Molecules float freely with and are impossible to get a definite mass or volume on an open sample.
In what ways does climate science differ from traditional sciences such as chemistry and biology?
Well chemistry is the study of chemicals and elements molecules and such and how they react with each other and what they do biology is the study of life and climate science is the study of weather paterns and well climate of certain regions?
Molecules of acetone and propyl aldehyde are both made from 3 carbon atoms 6 hydrogen atoms and 1 oxygen atom. The molecules differ in their arrangement of atoms. How do formulas show this?
The molecular formula, C3H6O, obviously does not show the difference between the isomers. You can draw a full structural formula for each of them, but we also can simply group the atoms to show their positions, viz CH3COCH3 for acetone and C2H5CHO for propionaldehyde.
Do molecules of ice have less mass than the molecules of water?
Mass is just "the amount of stuff there is". We can measure it in kg. If I have 4kg ice and 4kg water, then the answer is "no", but I could just as easily have 4kg of ice and 5kg water, in which case the answer is "yes". If you mean "does freezing water make it heavier?", then the answer is no - 4kg water makes 4kg ice, and they will weigh the same. However, ice has a greater volume than water*, so freezing water will make it expand. *This is not true for every liquid/solid combo.

Why do polar and nonpolar molecules have different properies?
compounds differ because of differences in attractions between their molecules.

How do the molecules in solids liquids gases differ?
The molecules remain identical (for example ice, water, vapors).
How do organic compounds differ from organic molecules?
Both are the same.
