Properties of Solids
Shape: Definite, Volume: Definite, Energy: Low
Properties of Liquids
Shape: Indefinite, Volume: Definite, Energy: Medium
Properties of Gasses
Shape: Indefinite, Volume: Indefinite, Energy: High
Gas particles
Small, hard spheres with insignificant volume
The motion of gas particles
Rapid, constant, and random
Gas particle collisions
Elastic so no energy is lost
Standard pressure
1 atm
Standard Temperature
273 K
What to use when measuring gas
Moles, pressure, temperature, and volume
Volume, V
Liters (also see as mL)
Temperature, T
Kelvin (also seen as C)
Pressure, P
atm (also seen as mmHg, kPa, and torr)
Charles’ Law
Measured with Volume and temperature and is directly proportional.
Boyle’s Law
Mesures with pressure and volume and is indirectly proportional.
Gay-Lussac’s Law
Measures with pressure and temperature and is directly proportional.
