Liquids
What is Cohesion?
When the particles in liquids attract a surface
What are intermolecular forces?
The electrostatic attractions between molecules.
What is the kinetic-molecular theory of matter ?
The theory says that solids are always moving and vibrating.
What is my favorite number.
12
What is Adhesion?
When the particles of the liquids and the particles of other materials attract between them.
Are electrostatic forces weaker or stronger than the forces that hold molecules together?
Weaker.
Do solids resist compression?
Since solids are so dense and have fixed shapes and definite volume, they do resist compression.
If I was an animal, which one would I be ?
(hint: white and black)
Penguin
What is Vaporization and Condensation ?
Vaporization: When a liquid goes to gaseous state, it happens at higher temperatures.
Condensation: when a gaseous substance goes to liquid state.
Name the groups in which the intermolecular forces are classified into.
Dipole-Dipole Forces
Hydrogen Bonds
Dispersion (London) Forces
How are crystals shaped ?
Crystals are shaped by electrical forces.
What is the lattice energy of a crystal?
It is the energy released when gaseous particles form crystals.
What is Critical Temperature and Critical Pressure ??
TC: The highest temperature that a gas can have, when it is liquefied.
Pc: The pressure that is needed to liquefy a gas.
How much time do electrons spend around an atom in a non polar bond?
They spend an equal amount of time around an atom.
What are Crystalline and Amorphous solids ?
How many sisters do I have ?
4
What is the boiling point of water at sea level ?
At sea level, water boils at 212°F
How much energy do Hydrogen Bonds create in water ?
20000 J/mol.
Name the five types of crystalline solids.
Atomic, covalent molecular, covalent network, ionic, and metallic.
