How Dense Are You?
I can't stand the pressure
What state is that?
The force is strong here
In theory that would work
100
What are two measurements are needed to calculate density
What is mass and volume
100
What are two measurements are needed to calculate pressure
What is force and area
100
What are the three states of matter
What are solid. liquid and gas
100
What are the units of force
What is a newton
100
What does KMT stand for
What is kinetic molecular theory

Water has a density of 1.0g/mL. What happens when you throw an object with a density of .95g/mL into it?
The object will float
200
How does pressure change with an increase in volume and why
What is the pressure decreases because you have the same amount of particles in a bigger space
200
Dry ice is solid CO2 which goes straight to a gas. What change of state of this...
What is sublimation
200
What is a force
A push or a pull
200
What is viscosity
a fluids resistance to flow
300
Explain how you would find the density of a rock
Use water displacement for the volume and find the mass using a scale. Mass divided by volume
300
What happens to the particles in a bottle when pressure is applied to it
The particles move closer together
300
What are the conditions for shape, volume, spaces between particles and movement of particles for a solid
What is fixed shape, fixed volume, very little spaces between particles, particles only vibrate
300
Explain the two types of forces
What is action at a distance forces can act on objects they don't touch contact forces have an effect only on objects they touch
300
How does temperature affect viscosity
The higher the temperature the easier it is to flow and the lower the viscosity
400
Explain why hot air rises
When you increase the temperature the particles move further apart. You now have less mass for the same volume. This decreases the density.

Calculate the amount of pressure exerted by a wooden crate that weighs 1200N and has a base with dimensions 4m by 3m.
100N
400
What happens to matter when it is heated and cooled
What is thermal expansion: more space between particles, particles move faster Thermal contraction: less space between particle, particles move slower
400
What are two types of action at a distance and contact forces
What is action at a distance: gravitational, magnetic, static contact: friction, tension, elastic
400
Which is easier to compress and why water or air
Air because there are more spaces between particles
500
Which are less dense gases or liquids and why?
Gases because there are less particles for the same amount of volume
500
If an object with a force of 200N has a pressure of 50N and the platform it sits on has a length of 2m what is the width?
What is 2m
500
What does the Kinetic molecular theory explain
How particles change when heat is added or removed
500
Calculate the force of an object that has an area of 25m2 and a pressure of 12Pa
What is 300N
500
Why does your bike tire feel flatter in the morning if you leave it outside at night.
As the temperature decreases so does the speed of the molecules and the space they take up. There is less pressure against the sides of the tire wall.
