Properties of Water Composition of Water Water as a Solvent Water Molecules Like Each Other
100
What is water?
Two atoms of hydrogen and one atom of oxygen make up this life-giving molecule.`
100
What is electrolysis?
The use of electricity to break a molecule down into smaller units.
100
What is a solution?
A substance dissolved in a liquid.
100
What is cohesion?
The phenomenon that occurs when individual molecules are so strongly attracted to each other that they tend to stay together.
200
What is glucose?
Another name for sugar.
200
What is Epsom salt?
The specific type of salt used in an experiment to determine the chemical composition of water that helps the water conduct electricity.
200
What is a solvent?
A component of a solution that dissolves other substances of which water is considered the best.
200
What is surface tension?
The effect of cohesion at the surface of a liqud.
300
What is a polar molecule?
A molecule that has slight positive and negative charges due to an imbalance in the way the electrons are shared.
300
What is experimental failure?
When there is a problem in an experiment that causes the experiment to fail or results to be inaccurate.
300
What is a solute?
A solid, liquid or gas that can be dissolved in a solvent.
300
What is gas?
All chemically similar molecules except for water take on this form at room temperature.
400
What is a positive charge?
Because the oxygen atom is stronger in a water molecule, the hydrogen atoms end up with this kind of charge.
400
What is peer review?
When several scientists complete the same experiment to make sure there are no errors.
400
What is dissolving?
This action occurs when water molecules are attracted to the electrical charges in the solute molecules.
400
What is a hydrogen bond?
A weaker connection between the oxygen atom in one water molecule and the hydrogen atom in another water molecule.
500
What is a nonpolar molecule?
In this molecule, the atoms in vegetable oil are shared equally and are not affected by electrical charges
500
What is cold fusion?
Drs. Martin Fleischmann and Stanley Pons thought they had created an inexpensive and limitless source of this type of nuclear energy.
500
What is an ionic compound
Ions that form charged particles when an atom loses or gains electrons and are held together by electrostatic forces.
500
What is a nonpolar molecule?
Because water does not dissolve gasoline, it is likely made up of this type of molecule.
