Science - Claire - Density and Physical Properties
matter
This book is _____________________ because its mass and volume.
Density; Density
______________ determines whether a substance will sink or float when placed in a second substance. The substance with less ______________ will always float.
Physical Property
Color is an example of a (n) _______________________ because color can be observed without changing the identity of a substance.
magnets
Copper and plastics are not attracted to ________________, but iron is.
Volume
Measurement of the amount of space an object takes up and is measured in milliliters (mL) or cm^3.
Mass
A measurement of the amount of matter (or stuff) in an object. It is measured in grams - not the same as weight.
conductors, restrict
Aluminum and copper are good _____________________. Glass, rubber, and plastic are poor conductors. Materials that are poor conductors _____________ the flow of heat and electricity.
weight
An object's _______________ is caused by the pull of gravity.
Conductivity
Another example of a physical property is _________________, which is the ability of the material to transmit head and electricity.
Displacement
If an object has an irregular shape, its volume can be found by ____________________________. How much water an object displaces is measured using a graduated cylinder.
Density
Mass divided by volume
Balance
Mass is measured using a ___________________.
atoms
Matter is made of particles called ________________.
hardness
The _____________________ that material is, the more it resists scratching.
Conductivity
The ability of a material to transfer heat and electricity is called _________________.
Malleability
The ability to be ________________, flattened or hammered without breaking is also a physical property. This is called _________________________.
malleability
The ability to be bent, flattened, or hammered without breaking is called ______________________.
Ductivity
The ability to be drawn into wires is called ________________.
mass
The amount of matter in an object is its ____________.
Weight
The amount of matter in an object is its ________________
mass
The amount of space that an object takes up is its _________________.
Democritus
The ancient Greek philosopher _______________________ thought that the universe was made of empty space and tiny bits of stuff that could not be divided into smaller pieces.
doiamonds
The hardest substances are _________________.
liquid; gas
The properties of a substance that can be observed without changing the identity of the object are called physical properties. These properties include the states of matter, which are solid, _____________ and _____________.
Volume
The pull of gravity on mass causes the object's ________________.
multiplying
The volume of a rectangular solid can be found by ______________________ its length by its width by its height.
space
The volume of matter is the amount of ______________ it takes up.
Newtons
Weight is measured in units of _________________ or pounds.
buoyant force
When an object is placed in a fluid, the fluid pushes the object. The push is called __________________.
Gold
When gold is dropped into a glass of milk, which substance will sink?
Gasoline
When milk is mixed with gasoline, which substance will float?
The ice has less density.
Why do ice cubes always float on top of a glass of water?
Density
is a comparison of how much matter there is in a certain amount of space.
Density
is measured as the mass of an object divided by its volume.
