Experience 1: The particle Nature of Matter Review

In which state do particles vibrate in a fixed position

Solid

What is matter made up of?

Particles gat are too snall to be seen

Anything that has mass and takes up space.

Matter

The space occupied by a material is its

Volune

The simplest form of matter containing only one type of atom with its own particular set of properties is called

An element

What are the three states of matter?

solid, liquid, gas

In which state do particles vibrate in a fixed position?

Solid

Particles in which state are arranged in a regular pattern and are held together by attraction forces?

Solid

Particles in which state are not attracted to one another and moving freely?

Gas

A state of matter that has definite shape and volume

Solid

A measure of how much mass is contained in a given unit of volume

Density

Define a liquid

Definite volume, indefinite shape

Select all the options that ARE NOT made out of matter

Heat, sound

When a liquid becomes a solid, what ads the changes in the behavior of the particles? Select Ll that apply

Particles lose energy, particles move closer together

When ice melts... select all that apply

The particles gain energy, the arrangement of the particles changes, the composition of the substance stays the same

Which state of the matter has the greatest potential energy?

Solid

Which state of the matter has the greatest kinetic energy?

Gas

How many atoms are in methane, CH4

5

Which molecules has the fewest number of atoms

HBr

An intensive property of matter

Doesn't depend on the amount of substance

examples of extensive properties

Mass, volume

Examples of physical changes

Vaporization, melting

The beaker filled with water

A student is in lab, observing a beaker filled with water as its boiling on a hot plate. What can be considered part of the surrounding?

The hot plate, the lab room
