100
the state of change directly from a solid to a gas
What is sublimation
100
says that if temperature is held constant and you decrease the volume of a container, pressure will increase
Who is Boyle
100
solve for R PV=nRT
R=PV/nT
100
Definite shape and definite volume
What is solid
100
is always used as the unit for temperature in gas law equations
What is kelvin
200
measure of a fluid's resistance to flow
What is viscosity
200
says that pressure applied to a fluid is transmitted through the fluid
Who is Pascal
200
solve for A P=F/A
A=FP
200
Indefinite shape and indefinite volume
What is gas
200
the force exerted per unit area
What is pressure
300
the measure of the total energy of the particles of a substance
What is thermal energy
300
says that as temperature increases (if the container can't expand/volume can't increase), the pressure increases
Who is Gay-Lussac

A small balloon is inflated with helium at 98 kPa to a volume of 2.0 L. According to the balloon's manufacturer, if the balloon is stretched to a volume of 4.5L, the balloon will pop. If the balloon were released, at what pressure would the balloon? Assume the temperature remains the same.
P2=43.56
300
indefinite shape and definite volume
What is liquid
300
spreading of particles until evenly distributed
What is diffusion
400
the amount of energy required to change a liquid to a gas
What is heat of vaporization
400
says that the buoyant force on an object is equal to the weight of the fluid displaced
Who is Archimedies

A gas with an initial temperature of 50 degrees C, is warmed to 105 degrees C. If the final volume was 5.1L, what was the initial volume of the gas? Assume the pressure remains constant.
V1=4.36L
400
Example of heat of fusion
What is melting
400
object that doesn't have a definite melting point
What is amorphous
500
the amount of energy required to change a solid to a liquid
What is heat of fusion
500
says that as velocity of a fluid increases, the pressure exerted by the fluid decreased
Who is Bernoulli
500
A sample of gas has a volume of 70L at 0 degrees C. If pressure is held constant, what is the new volume if the temperature is increased to 100 degrees C.
V2=95.64L
500
example of heat of vaporization
What is boiling
500
Explain the relationship between density and buoyancy
less dense than water it will float and more dense than water it will sink
