List four properties of gas
What is Gases expand to fill their containers, they spread out easily and mix with one another, they have low densities and are compressible, and unlike solids and liquids, gases are mostly empty space.
200
Volume increases and gas increases at a constant pressure
What is Charles's Law
200
Give two examples of each state of matter
What is Solid= Ice and Chair, Liquid= Water and Kool-Aid, Gas= Oxygen and Water Vapor, Plasma= Lightning and the Aurora Borealis.

Define Boiling
What is the process in which a liquid changes to a gas, particles move faster
200
True or false. The buoyant force is the upward force that keeps an object immersed in or floating in a fluid.
What is True
200
Identify what causes the pressure exerted by gas molecules on their container
What is the volume
300
The buoyant force on an object in a fluid is an upward force equal to the weight of the fluid that the object displaces
What is Archimedes Prinicple
300
Describe the relation between temperature and kinetic energy.
What is Temperature is a measure of average kinetic energy of the particles in an object.
300
Define Sublimation
What is the process in which a solid changes directly into a gas, particles move extremely fast and freely

What is resistance of gas or liquid to flow
400
Describe how gases are different from solids and liquids and give examples
What is Gases can change shape and volume, liquids can change shape but not volume, and solids have a definite shape and volume.
500
As pressure increases, the temperature increases. Volume is constant. Name the law.
What is Gay-Lussac's Law
500
Define energy
What is the capacity to do work.

State whether energy is released or whether energy is required for the following changes of state to take place. Melting, Evaporation, Sublimation, and Condensation
What is a.
Melting- energy is required
Evaporation- energy is required
Sublimation- energy is required
Condensation- energy is released
500
Explain how differences in fluid pressure create buoyant force on an object
What is fluid pressure increases with depth and the forces pushing up on the object are greater than the forces pushing down on the object.
