universal room temperature
25°C
the force exerted by air molecules in Earth’s atmosphere against a surface. It is also known as air pressure
Atmospheric Pressure
standard surrounding pressure/atmospheric pressure.
1 atm
state of matter that features closely packed or compactly arranged atoms
Solid
state of matter that has a definite volume, but no fixed shape. It follows the shape of the container.
Liquid
state of matter that has no fixed shape or volume. Normally, it fills up the container’s volume; no shape.
Gas
In the Physical Characteristics of Gases, gasses assume the __________ of their containers.
volume and shape
In the Physical Characteristics of Gases, gases are the most _____ state of matter.
compressible
In the Physical Characteristics of Gases, gases will mix _________ when confined to the same container.
evenly and completely
In the Physical Characteristics of Gases, gases have much lower ______ than liquids and solid
densities
Law for Volume + Pressure
Boyle’s Law
Law for Volume + Temperature
Charles’ Law
Law for Temperature + Pressure
Gay Lussac’s or Amonoton’s Law
Law for Amount + Volume
Avogadro’s Law
Law for Amount (mole) + Temperature + Volume + Pressure
Ideal Gas Law
Law for Pressure
Dalton’s Law
the amount of force applied to an area
Pressure
These units are literally the difference in the heights measured in mm (h) of two connected columns of mercury.
mm Hg or torr
Higher sea level =
lower atm
