Boyle's Law
For a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases.
Charles Law
For a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature increases.
Gay-Lussac's Law
For a fixed amount of gas at a constant volume, the pressure of the gas increases as the temperature increases.
Temperature
the average kinetic energy of gas particles. (i.e. how fast the particles move); ALWAYS USE KELVIN
Pressure
the force of gas particles hitting against the walls of the container; Make Units Match
Volume
how much space the gas occupies (Remember, a gas fills the volume of its container.); Use Liters
Boyle's Law
P1V1 = P2V2
Charles Law
V1/T1 = V2/T2
Gay-Lussac's Law Equation
P1/T1 = P2 /T2
Combined Gas Law Equation
P1V1/T1= P2V2/T2
Kinetic Molecular Theory
1) mass no volume 2) no forces exerted 3) constant, random motion 4) elastic collisions 5) kinetic energy based on temperature regardless of gas
True
True or False: If you have a balloon inside a car at noon during a hot summer day, the molecules inside the balloon will increase in pressure.
Increases
As the volume of confined gas decreases at constant temperature, the pressure exerted by the gas___________.
Boyle's Law
Which gas law is involved when a balloon pops after being sat on?
Kelvin
unit of measurement used for temperature
moles
unit of measurement represented by "n"
atmosphere
unit of measurement used to describe pressure
liters
unit of measurement used to describe volume
0 degrees C
Standard temperature
1 atmosphere
Standard pressure
sitting at your desk
Where would there be more air pressure - sitting at your desk, Boulder City Colorado or on top of a mountain?
Faster
Heating up the molecules of a gas allow the particles to move......
MORE pressure
If MORE gas molecules created MORE collisions with the sides of a container, then there will be_____
Burst because increased altitude will decrease external pressure allowing the internal pressure of the balloon to expand the balloon beyond its capacity.
A fly away balloon will eventually ......
