I like to Move It
100
This is anything that takes up space (and has mass).
What is matter?
100
In this state of matter, particles are packed very tightly together and can barely move.
What is a solid?
100
This is the process of a solid turning into a liquid.
What is melting?
100
This type of heat transfer happens when a hotter material moves towards a cooler area; NO direct contact.
What is convection?
100
When a thermometer is placed in a substance, it is measuring this.
What is temperature?
200
Everything in existence is made up of these.
What are atoms or particles?
200
Substances in this state of matter have NO definite volume and NO definite shape.
What is a gas?
200
This is the process of a liquid turning into a gas.
What is evaporation?
200
When these types of changes take place, the substance does NOT change into a new substance. These types of changes can usually be undone or reversed.
What are physical changes?
200
If molecules in a substance increase their speed, its temperature will do this.
What is the temperature will increase?
300
These are the three most common states of matter.
What are solids, liquids and gases?
300
Matter in this state has a definite volume, but NOT a definite shape.
What is a liquid?
300
This is the process of a gas turning into a liquid.
What is condensation?
300
During this type of change, a chemical reaction takes place, and a new substance is formed. These types of changes are impossible or difficult to reverse.
What are chemical changes?
300
When there are two substances/objects of different temperatures (one is warm, one is cool), thermal energy will always transfer this way.
What is from the warmer substance/object to the cooler substance/object?
400
The amount of matter something contains is this.
What is its mass?
400
In this state of matter, molecules are the furthest apart.
What is gas?
400
This is the process of a liquid turning into a solid.
What is freezing or solidification?
400
Changes in states of matter happen when this is added or removed.
What is when heat is added or removed?
400
This type of heat transfer occurs through open space, without movement from hotter to cooler areas or direct contact.
What is radiation?
500
This is the amount of space something takes up.
What is volume?
500
This state of matter has a definite volume but NO definite shape.
What is a liquid?
500
As water molecules freeze, this happens to their speed.
What is the water molecules slow down?
500
These TWO physical changes can be caused by ADDING heat.
What are evaporation and melting?
500
This type of heat transfer happens when heat moves through direct contact.
What is conduction?
600
These are observable events that occur in nature; these events make us wonder and inspire curiosity!
What are phenomena?
600
Matter in this state has the ability to glow.
What is plasma?
600
This is the freezing point of water on the Celsius scale.
What is 0o Celsius?
600
These TWO physical changes are caused by REMOVING heat.
What are condensation and freezing?
600
This is the average kinetic energy of the molecules in a substance.
What is temperature?
