Science unit 2C quiz

What property allows you to describe liquids and gases as fluids

Fluid means able to flow. Because liquid and gas particles are not held rigidly in place they have the freedom of movement and can flow

Describe a solid

-Particles vibrate while rigidly being held in place -Has a fixed shape and volume -particles are closely spaced -low compressibility and high density - particles are crystalline or amorphous

Compare the degree of motion of the particles in solids, liquids, and gases

-Solids are closely spaced, held rigidly in place, move only vibrating -liquids Are closely spaced and move by vibrating and sliding past each other -gases are widely spaced and move freely and rapidly

What is viscosity

A fluids resistance to flowing

Plasma

A gas like state of matter , formed at very high temperatures, that consists of high energy ions and free electrons

What is a plasma

A high energy state of matter similar to a gas except that it is made up of ions and free electrons

What state of matter has changeable shape, low compressibility, and fixed volume?

Liquid

amorphous

Particles have no regular arrangement

crystalline solid

Solid particles are arranged in a regular repeating pattern

What are the states of matter

Solid, liquid, gas

liquid

State of matter in which particles are close together but able to move around

What factors determine the state of a substance?

The relationship between the kinetic energy of the substances particles and the attractive forces between those particles

Gas

The state of matter in which particles are far apart, move rapidly, and have little interaction with each other

solid

the state of matter in which particles vibrate in fixed positions , giving a substance a fixed shape and volume
