Floating & Sinking
If an object is denser than water, it will do this
Sink
Opposite poles do this to each other
Attract
This state of matter has both a definite shape AND a definite volume
Solid
A change that alters the appearance or state of matter without creating a new substance is this type of change
Physical change
This term describes a combination of two or more types of matter
Mixture
An object will float in water if its density is this compared to water
Less dense
When two North poles or two South poles are placed near each other, they will do this
Repel
This state of matter has NO definite shape and NO definite volume
Gas
An apple rotting on the counter is an example of this type of change
Chemical change
"All solutions are mixtures, but NOT all mixtures are..."
Solutions
This term refers to the amount of mass contained within a certain volume
Density
Earth's core creates a magnetic field because it contains this magnetic metal
Iron/Nickel
This state of matter has a definite volume, but NO definite shape, taking the shape of its container
Liquid
When water vapor condenses into a cloud, it is undergoing this type of change
Physical change
To become evenly mixed with another form of matter is the definition of...
Dissolve
A solid steel ball sinks in water, but a steel bowl of the same mass floats because its mass is spread over a larger one of these
Area (or surface area)
Besides iron, these are the other two magnetic metals
Nickel and Cobalt
In this state of matter, particles are tightly packed together in a fixed, rigid structure
Solid
Rust forming on a bicycle is a chemical change because it produces a new substance with new ones of these
Properties
If Mr. Squiggles mixes 50 g of nuts with 25 g of chocolate candies, the total mass of the mixture will be this amount
75 grams
A steel bowl floats because spreading its mass over a larger area allows it to push against more of this
Water
What do you call the area around a magnet where objects are attracted or repelled?
Magnetic field
What is the fourth state of matter?
Plasma
Cutting up various fruits to make a fruit salad is an example of a physical change because it does not create a new one of these
Substance
The Law of Conservation of Mass states that when items are mixed together, their total mass does this
Is conserved (stays the same)
