Solids and Liquids Flashcards
The attraction between liquid particles is caused by…
Intermolecular particles
The three types of intermolecular forces are…
London dispersion forces, dipole-dipole forces, and hydrogen bonding.
Are liquid particles bound in fixed position?
No, they move around constantly.
What is the density of liquids?
Relatively high
Can liquids diffuse?
Yes, just at a slower rate.
What is surface tension?
A force that pulls adjacent parts of a liquid’s surface together, decreasing surface area to the smallest possible size.
The higher the force of attraction between the particles of a liquid…
The higher the surface tension is.
What is capillary action?
Attraction of a liquid to the surface of a solid that tends to pull the molecules upward against the pull of gravity.
A concave liquid surface that forms in the test tube or cylinder is called a…
Meniscus.
Attractive forces tend to hold the particle of a solid in a ….
Fixed position.
What are the two types of solids?
Crystalline solids, and amorphous solids.
What are crystalline solids?
particles arranged in an orderly, geometric, repeating pattern.
What are amorphous solids?
particles arranged randomly; has no definite melting point.
What’s another name for an amorphous solid?
A supercooled liquid.
What phase change is a gas to a liquid?
Sublimation.
