What best describes a fluid?

• A substance that holds its shape and resists flow

• A substance that flows and takes the shape of its container

• A solid with high elasticity

• A gas that behaves like a solid

What happens to pressure as you go deeper in a fluid?

• It decreases

• It stays constant

• It increases

• It becomes zero

What is the density of a substance?

• The weight of an object

• The force applied to a fluid

• The mass per unit volume

• The temperature of the fluid

When an object floats in water, it is because?

• It is heavier than water

• Water has no force acting on objects

• It is less dense than water

• Air is trapped inside it

What does viscosity measure in a fluid?

• The fluid's color
