Study Notes
Kinetic Theories of Matter
- Matter is composed of tiny particles (atoms or molecules) in constant, random motion.
- Kinetic energy of these particles increases with temperature, leading to increased particle motion.
- Particles collide with each other and the container walls, transferring energy.
Graham's Law of Effusion/Diffusion
- Effusion is the escape of a gas through a tiny opening.
- Diffusion is the spontaneous mixing of gases.
- The rate of effusion and diffusion of a gas is inversely proportional to the square root of its molar mass.
Boyle's Law
- At constant temperature, the pressure of a fixed amount of gas is inversely proportional to its volume.
- P1V1 = P2V2
Charles's Law
- At constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature.
- V1/T1 = V2/T2
Avogadro's Law
- Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
General Gas Law
- Combines Boyle's, Charles's, and Avogadro's laws to relate pressure, volume, temperature, and amount of gas.
Ideal Gas Law
- PV = nRT
- P = pressure
- V = volume
- n = number of moles
- R = ideal gas constant
- T = absolute temperature(Kelvin)
Deviation from the Ideal Gas Law
- Ideal gas law assumes gas particles have negligible volume and no attraction between them.
- Real gases deviate from ideal behavior at high pressure and low temperature due to particle volume and intermolecular forces.
Dalton's Law of Partial Pressures
- Total pressure of a mixture of gases is the sum of the partial pressures of the individual gases.
- Ptotal = P1 + P2 + P3...
