Question | Answer |
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. |
