You can find the mass of an object by using a _________.
What is a balance?
200
Malleable is to copper as flammable is to _____________.
What is wood (or other material that burns)?
200
In this state of matter, the particles move fast enough to break away from each other and move in different directions.
What is gas?
200
A substance freezes and melts at the same _______________.
What is temperature?
300
The amount of space that something takes up.
What is volume?
300
This can be found using the following formula: mass divided by volume.
What is density?
300
The properties of matter that can be seen or measured without changing the substance into something else.
What are physical properties?
300
In this state of matter, particles have electric charges and therefore can conduct electricity.
What is plasma?
300
Ice cubes in a cooler melt more slowly than ice cubes left out on a tray. This is because the cooler is ______________.
What is insulated? The insulation of the cooler slows the flow of heat into the ice cubes.
400

What is a pound of lead?
400
As wood burns, it will change into a new substance - ash and gasses. A substance's ability to burn is called ______________.
What is flammability?
400
The ________ of the particles and how strongly they are attracted to one another determine whether the matter is a solid, liquid, gas, or plasma.
What is speed (or energy)?
400
The change of state from a gas to a liquid is called ___________.
What is condensation?
500
The _________ of a clay ball would not change if the clay is spread into the shape of a pancake.
What is mass? The mass of an object remains the same and does not depend on the object's shape.
500
This can change if the object moves to a place with a different force of gravity.
What is weight?
500
The specific way a substance changes when mixed with another substance is a ______________ property.
What is a chemical property?
500
