# Density by GK

### Physical Science Density

What is the definition of density? amount of mass in a given volume of a substance
What is mass? amount of matter
What is volume? amount of space taken up
As mass increases, what happens to the density? density also increases
What happens to density as volume increases? density decreases
Density and mass have what kind of relationship? direct relationship
Density and volume have what kind of relationship? inverse relationship
A fluid is anything that can do what? flow
Which two states of matter are fluids? liquids and gases
Liquids are fluids because they can do what? flow
What is the density of water? 1.0 g/cm cubed
What density is needed for something to float in water? less than 1.0 g/cm cubed
What density is needed for something to sink in water? greater than 1.0 g/cm cubed
What is the formula for density? mass divided by volume
The formula for the volume of any type of solid rectangular object is what? L x W x H
The densities of which things are always the same? pure substances
Which substances are pure substances? elements and compounds
Why can the density of a pure substance be used to identify the substance? Its density does not change
What is the upward force of a fluid on an object immersed in the fluid called? the buoyant force
Archimedes' principle states that the buoyant force exerted on an immersed object is equal to what? the weight of the immersed object
Using a graduated cylinder and water to measure volume is called what? water displacement
What is the volume of an object that makes the water level in a graduated cylinder rise from 5 mL to 12 mL? 7 mL
What is the volume of an object that is 2 cm long, 3 cm wide, and 1 cm tall? 6 cm cubed
An object or substance will float in a fluid when the fluid's density is what? greater than the object or substance
Salt water is more dense than pure water because the salt adds to the water's mass without increasing its what? volume
