What is an element?

Back 7

An element is on the periodic table of elements.

Front 8

What is a Homogneous mixture?

Back 8

Homogneous is where you can't see all of the different components that make it up. Eg.milk

Front 9

What is a mixture?

Back 9

A mixture contains at least two types of substances or two different types of particles.

What is an atom?

Back 10

An atom is the smallest unit of matter that has the properties of an element.

Front 11

What is a molecule?

Back 11

Molecules form when two or more atoms form chemical bonds with each other.

Front 12

What is a Heterogeneous mixture?

Back 12

It is where you can see all of the parts that make it up. Eg.Pizza

Front 13

What is Evaporation?

Back 13

Evaporation is when a liquid changes state into a gas.

Front 14

What is condensation?

Back 14

It is where water that collects as droplets on a cold surface when humid air is in contact with it.

Front 15

What is Sublimation?

Back 15

A substance changes from a solid to a gas without ever passing through a liquid phase. Eg.Dry ice

Front 16

What is Conductivity?

Back 16

It measures the water's ability to conduct electricity.

Front 17

What is Precipitate?

Back 17

A precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation.

Front 18

What is the Particle Theory Of Matter?

Back 18

1. All matter is made up of tiny particles.

2. All particles of one substance are the same. Different substances are made up of different particles.

3. The particles are always moving. The more energy the particles have, the faster they move.

What is it called from a liquid to a solid?

Back 25

Freezing

Front 26

What are the Chemical properties of matter?

Back 26

Are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Nearly impossible to change the state back to the original once changed.
