false, they can take multiple/whatever it is put into.
What is density?
The density of a substance is its mass per unit volume.
What is a fluid?
A fluid is a material that can easily flow.
What is pressure?
Pressure is equal to the force exerted on a surface divided by the total area over which the force is exerted.
True or false
Air is a liquid
True
What is the equation for Pascals?
1N/m squared
Name four examples of a fluid.
Answers may vary.
air, water,oil,juice, etc.
What is the equation for pressure?
Pressure = force/area
What makes fluids flow?
A fluid naturally flows from an area of high pressure to an area of low pressure.
What is Bernoulli's Principle?
Bernoulli's Principle states that the faster a fluid moves, the less pressure the fluid exerts.
What happens when you drink from a straw?
When you start to sip, you remove the air from the straw. This creates an area of low pressure in the straw. The higher air pressure pushing down on the surface of your drink forces the drink up into the straw.
What is the equation for density?
Mass/volume
