Gas Laws Quiz

Gas Laws

• Boyle's Law: The volume of a gas is inversely proportional to the pressure, at constant temperature.
  • V1 / V2 = P2 / P1
• Charles' Law: The volume of a gas is directly proportional to the temperature, at constant pressure.
  • V1 / V2 = T1 / T2
• Gay-Lussac's Law: The pressure of a gas is directly proportional to the temperature, at constant volume.
  • P1 / P2 = T1 / T2
• Avogadro's Law: The volume of a gas is directly proportional to the number of moles, at constant pressure and temperature.
  • V1 / V2 = n1 / n2
• Ideal Gas Law: A combination of the above laws, describing the behavior of an ideal gas.
  • PV = nRT

States of Matter

• Solid: Particles are closely packed and have a fixed position.
• Liquid: Particles are close together but can move past each other.
• Gas: Particles are widely spaced and can move freely.
• Plasma: Particles are ionized and can move freely.

Gas Properties

• Diffusion: The ability of gases to mix and spread out.
• Effusion: The ability of gases to escape through a small opening.
• Expansion: The ability of gases to expand and fill their container.
• Compressibility: The ability of gases to be compressed to a smaller volume.
• Viscosity: The measure of a gas's resistance to flow.
• Thermal Conductivity: The ability of gases to conduct heat.
• Specific Heat Capacity: The amount of heat energy required to change the temperature of a gas by 1°C.

Gas Laws

• Boyle's Law: The volume of a gas is inversely proportional to the pressure, at constant temperature, expressed as V1 / V2 = P2 / P1.
• Charles' Law: The volume of a gas is directly proportional to the temperature, at constant pressure, expressed as V1 / V2 = T1 / T2.
• Gay-Lussac's Law: The pressure of a gas is directly proportional to the temperature, at constant volume, expressed as P1 / P2 = T1 / T2.
