Liquids

Explain the relatively high density of liquids.

Liquids have a higher density than gas, but a lower one than solids. They have a closer arrangement of liquid particles.

What is evaporation?

The formation of vaporization by which particles escape from the surface of a non bonding liquid --caused by heating which occurs on the top

What is vaporization?

The process by which a liquid or a solid changes to a gas

What is a liquid?

a form that has a definite volume and takes the shape of its container

What is a fluid?

a liquid or as because they can move around each other

Explain a liquid's ability to diffuse.

any liquid gradually diffuses throughout another liquid in which it can dissolve

Explain a liquid's ability to diffuse in relation to gases and solids.

gases; slower because the particles of a liquid are much closer together solid; faster because the molecules in a liquid are much more spread out than that of a solid

What happens to diffusion of a liquid when the temperature is increased?

it goes more quickly because the particles are more excited with energy and are faster in moving about from each other

Explain a liquid's relative incompressibility.

liquids are much less compressible than gases because liquid particles are more closely packed together liquids can transmit pressure equally in all directions

What is the surface tension of liquids?

surface tension is a force that tends to pull adjacent parts of a liquid's surface together

The attractive forces between particles in a liquid are more effective than particles between a gas because...

the attraction is caused by dipole dipole forces, london dispersion forces, and hydrogen bonding

What does surface tension result from?

the attractive forces between the particles of a liquid the higher the attraction, the higher the surface tension

What is boiling?

the change of a liquid to bubbles of vapor that appear throughout the liquid -- caused by heating which occurs on the bottom

How does a liquid form a solid?

when a liquid is cooled the average kinetic energy of its particles decrease and the particles slow enough to form a solid

What is freezing?

when the kinetic energy of a solid is low enough, attractive forces pull the particles into a solid arrangement

What are some characteristics of the particles of liquids?

1. relatively high density (compared to a gas) 2. relatively incompressible (compared to a gas) 3. ability to diffuse (in comparison to gas or sold) 4. have surface tension
