Dalton's Law of Partial Pressure
At constant temperature and volume, the total pressure exerted by a mix of gases is equal to the sum of the partial pressures.
For a given mass of gas at a constant temperature, the volume varies inversely with the pressure.
The pressure of a gas is directly proportional to the Kelvin temperature if the volume is kept constant.
Combined Gas Law
A gas that remains a gas at any temperature or pressure (nonexistent)
Ideal Gas Law
Ideal Gas Law
Equal volumes of gasess at the same temperature and pressure contain the same number of particles.
The volume of a fixed mass is directly proportional to it's Kelvin temperature if the pressure is kept constant.
The ability to do work
SI unit for energy
Composed of particles, usually molecules or atoms which move rapidly in constant random motion, all collisions are perfectly elastic meaning all kinetic energy is transferred from one particle to another, during collisions the KE remains constant.
The amount of space occupied by matter.
SI Unit for volume
Measure of the average kinetic energy of particles in a substance.
SI unit of temperature
Temp at which all motion is said to stop, even electron's orbits. -273.
Force per unit area.
Result of simultaneous collisions of billions of particles on an object.
Space where no particles of matter exist.
the pressure exerted by the atmosphere, decreases with an increase in elevation.
Instrument used to measure atmospheric pressure.
Unit of pressure named after Torricelli who invented the barometer.
Millimeters of mercury, pressure needed to support a column of mercury 1 mm high.
a unit of measurement for pressure equal to 760 mm Hg.
SI Unit of pressure, 1 atm= 101.3 pascal
Free to move, attractive forces between particles.
Liquid changing to a gas below it's boiling point, cooling process.
Collision of particles within the walls of a sealed container.
When the rate of evaporation equals the rate of condensation.
Temperature at which the vapor pressure of the liquid is equal to the external pressure.
Normal Boiling Point
BP of any liquid at standard pressure (1atm)
Particles tend to vibrate around fixed points, dense and incompressible.
Temp at which a solid turns to a liquid.
Temperature at which a liquid turns to a solid.
Heat of Fusion
the amount of energy required to change a substance from the solid phase to the liquid phase at its melting point.
Change of substance from solid to directly to a gas
Two or more different molecular forms of the same element in the same physical state.
Gives conditions of T and P at which a substance exists in each state.T
Temperature, pressure at which all 3 states can exist in equillibrium.
