100

The phase of matter with no definite shape OR definite volume

What is a gas?

100
In this process matter changes state from a solid to a liquid

What is melting?

100

According to kinetic molecular theory, these make up all matter

What are small particles?

100

The formula to calculate Density

What is mass divided by volume?

100

The study of matter and its changes

What is chemistry?

200

The phase of matter in which particles have the least potential energy possible

What is a solid?

200

In this process vapor in the air becomes a liquid

What is condensation?

200

A description of atoms and molecules

Atoms are the smallest unit of matter, and molecules are groups of atoms bonded together.

200

The unit for density

What is g/mL or g/cm?

200

An explanation of how particles in matter behave

What is kinetic molecular theory?

300

The phase of matter with the most thermal (kinetic plus potential) energy

What is a gas?

300

An increase in this can cause a change in state

What are kinetic and potential energy?

Or

What are particle attraction and particle motion?

300

The particle arangement in the different states of matter

Solid-closely packed and vibrating

Liquid-close but sliding past each other

Gas-far apart not attracted to each other

300

Calculate the Density

Mass: 12g

Volume 3cm3

What 4g/cm3

300

Anything that takes up space and has mass

What is matter?

400

The phase of matter a substance would end as after the process of condensation.

What is a liquid?

400

In this process a liquid becomes a gas

What is vaporization?

400

How energy relates to particle movement

What is as the energy increases, the particles move faster and further apart?

400

Calculate the density

Mass: 24g

Volume: 4cm3

What is 6 g/cm3

400

The amount of space occupied by an object

What is volume?

500

The phase of matter a substance will end up as at the end of the process of deposition

What is a solid?

500

In this process matter changes from a solid to a gas, skipping the liquid state

What is sublimation?

500

The Key components of the kinetic molecular theory

All matter is made of small particles, that are in constant motion, that move more with more energy

500

Calculate the density

Mass: 12g

Volume 60mL

What is 5 g/mL ?

500

A characteristic of matter that can be measured or described with numerical value

The key components of the kinetic molecular theory are the constant motion of particles, their interactions, and their kinetic energy.
