Properties of Water | Composition of Water | Water as a Solvent | Water Molecules Like Each Other |
---|---|---|---|
What is water?
Two atoms of hydrogen and one atom of oxygen make up this life-giving molecule.`
|
What is electrolysis?
The use of electricity to break a molecule down into smaller units.
|
What is a solution?
A substance dissolved in a liquid.
|
What is cohesion?
The phenomenon that occurs when individual molecules are so strongly attracted to each other that they tend to stay together.
|
What is glucose?
Another name for sugar.
|
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.
|
What is a solvent?
A component of a solution that dissolves other substances of which water is considered the best.
|
What is surface tension?
The effect of cohesion at the surface of a liqud.
|
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.
|
What is experimental failure?
When there is a problem in an experiment that causes the experiment to fail or results to be inaccurate.
|
What is a solute?
A solid, liquid or gas that can be dissolved in a solvent.
|
What is gas?
All chemically similar molecules except for water take on this form at room temperature.
|
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.
|
What is peer review?
When several scientists complete the same experiment to make sure there are no errors.
|
What is dissolving?
This action occurs when water molecules are attracted to the electrical charges in the solute molecules.
|
What is a hydrogen bond?
A weaker connection between the oxygen atom in one water molecule and the hydrogen atom in another water molecule.
|
What is a nonpolar molecule?
In this molecule, the atoms in vegetable oil are shared equally and are not affected by electrical charges
|
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.
|
What is an ionic compound
Ions that form charged particles when an atom loses or gains electrons and are held together by electrostatic forces.
|
What is a nonpolar molecule?
Because water does not dissolve gasoline, it is likely made up of this type of molecule.
