What is the density of a rock that has a mass of 40g and a volume of 20ml?

2 g/cm³

If two object have the same mass and object 1 is smaller in volume than object 2, which object would have the higher density?

object 1

What happens to the density as molecules get more compact and closer together?

Density increases

What happens to density when you increase pressure?

Density increases

What happens to density when you heat an object?

Density decreases

If an object is less dense than water, what will happen to that object when placed in water?

It will float

What does the density of an object have to be in order for it to float (need a number)

less than 1 g/cm³

If you increase the pressure on an object, what happens to the mass of the object?

Nothing. Mass stays the same.

You start with 10ml of water in a graduated cylinder. You add an object into the graduated cylinder and the volume rises to 50ml. What is the volume of the object?

40ml

What happens to the volume of liquid water when it turns to ice?

volume increases

If a piece of wood is cut exactly in half, what will happen to the density of the wood?

Nothing. Density stays the same.

What does every graph need regardless of the type of graph?

Title

Each piece of ___________________ must have a different justification for why it supports the claim.

evidence

What will happen to the density of an object if you decrease only the volume of an object?

Density will increase

What will happen to the density of an object if you increase only the mass of the object?

Density will increase

What will happen to the density of an object if you decrease the mass and volume of an object 50%?

Density will stay the same
