Gas Laws
Increases
As the volume of confined gas decreases at constant temperature, the pressure exerted by the gas___________.
Charles's Law Definition
For a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature increases.
Boyle's Law Definition
For a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases.
Boyle's Law Equation
P1V1 = P2V2
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.
Charles's Law Equation
V1/T1 = V2/T2
Avogadro's Law Equation
V1/n1 = V2/n2
sitting at your desk
Where would there be more air pressure - sitting at your desk, Boulder City Colorado or on top of a mountain?
Volume
how much space the gas occupies. (Remember, a gas fills the volume of its container.); Use Liters
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 ......
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_____
Boyle's Law
Which gas law is involved when a balloon pops after being sat on?
Avogadro's Law Definition
equal volumes of all gases, at the same temperature and pressure, have the same number molecules
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
moles
unit of measurement represented by "n"
Kelvin (K)
unit of measurement used for temperature
atmosphere (atm)
unit of measurement used to describe pressure
liters (L)
unit of measurement used to describe volume
