# Density Flashcards

### Science

What is the definition of mass? Mass means the amount of matter in an object.
What is density? Density is the amount of matter contained in a unit of volume of a material.
What three factors affect density? The three factors that affect density are composition, temperature, and pressure.
What is composition? Composition is material that an object and how closely molecules are packed.
What are the three states of matter that can affect the density of an object? The three states of matter are solid, liquid and gas.
What is volume? Volume is the amount space taken up by an object.
When temperature increases, what density do? When heat goes up it means density goes down.
when temperature increases, what happens to the mass and volume of an object? Nothing happen to the mass yet the volume increases.
When pressure increases, what happens to the density of an object? The density goes up when under pressure.
When pressure increases, what happens to the mass and volume of an object? Nothing happens to the mass and the volume decreases
How does the object floating relate to density? When the object is lighter(less dense) than the surrounding substance it floats.
How does an object sinking relate to density? if an object is more dense than the surrounding substance, it will sink.
Are mass and weight the same thing? explain. No. because the mass is amount of matter and weight depends on gravity.
