Particle motions in a gas

• What do gas particles do in a container?

  They fly around and bump into things
• What happens when gas particles collide with each other?

  They exert a force on each other
• How does the kinetic theory describe matter?

  All matter is made of small, moving particles
• What is the characteristic of gas particles in terms of space?

  They hardly take up any space
• What is mostly present in a gas?

  Empty space
• What happens to gas particles as they move at high speeds?

  They bang into each other and walls
• What occurs when gas particles collide with something?

  They exert a force on that object
• What is the outward gas pressure in a sealed container?

  Total force exerted by gas particles
• What cannot change in a sealed container?

  Volume of gas
• What happens to gas pressure when temperature increases?

  Pressure increases as temperature rises
• How does increasing temperature affect gas particle movement?

  Particles move faster and collide more often
• What happens to gas pressure when volume increases?

  Pressure decreases as volume increases
• What is the relationship between pressure and volume?

  They are inversely proportional
• What is the formula relating pressure and volume?

  P₁V₁ = P₂V₂
• What units are used for pressure?

  Pascal (Pa) or N/m²
• What units are used for volume?

  Cubic meters (m³)
• What happens to gas pressure when volume decreases?

  Pressure increases as volume decreases
• What happens to gas particles when temperature increases?

  They gain energy and move faster
• What is absolute zero in terms of temperature?

  0 Kelvin
• What happens when you increase the temperature of a gas?

  Particles move more quickly and collide more
• What is the effect of increasing temperature on gas pressure?

  It increases the pressure of the gas
• What is the relationship between temperature, volume, and pressure in gases?

  • Pressure increases with decreasing volume
  • Pressure increases with increasing temperature
  • Volume increases with increasing temperature at constant pressure
• What are the key principles of gas behavior according to the kinetic theory?

  • Matter is made of small, moving particles
  • Gas particles occupy a large amount of empty space
  • Gas pressure is due to particle collisions
• What is the unit of pressure?

  Pascal (Pa)
• What is the unit of volume?

  Cubic meter (m³)
• What does absolute zero represent?

  It is the coldest possible temperature.
• What happens to particles when temperature increases?

  They gain energy and move more quickly.
• What happens to particles when temperature decreases?

  They lose energy and move more slowly.
• What is the coldest temperature that anything can reach?

  -273 °C
• What is the significance of absolute zero in terms of particle energy?

  Particles have minimal kinetic energy at absolute zero.
• What is the Kelvin scale's absolute zero value?

  0 K
• How does a temperature change of 1 °C relate to the Kelvin scale?

  It is equivalent to a change of 1 K.
• What is the difference between Celsius and Kelvin scales?

  The zero point is different for each scale.
• How do you convert Celsius to Kelvin?

  Add 273 to the Celsius temperature.
• How do you convert Kelvin to Celsius?

  Subtract 273 from the Kelvin temperature.
• What is the freezing point of water in Celsius?

  0 °C
• What is the boiling point of water in Celsius?

  100 °C
• What happens to gas particles as pressure increases?

  They move closer together and collide more frequently.
• How does the number of gas particles affect pressure?

  More particles increase the pressure in a container.
• What is the relationship between gas particle movement and pressure?

  Faster movement leads to higher pressure.
