Ideal Gasses

• Particle Theory

  • Particles in a gas are constantly moving at a high speed
  • A.K.A Brownian Motion
  • Movement is random
  • Constantly collide with each other
  • Also collide with the walls of the container
  • Ideal gases are assumed to behave in predictable ways

  A) Gas particles move randomly at high speed

  B) Often colliding with the wall of the container

  
• Absolutre Zero (Theoretical Minimum)

  • At absolute zero, particles have no kinetic energy
  • Will stop vibrating
  • Equivalent to -273°C or 0 Kelvin (K)
  • Kelving scale begins at -273°C
  • A temp change of 1°C is equivalent to 1K
  • C° to K --> add 273
  • K to C° --> subtract 273
• Gas Molecules and Kinetic Energy

  • There is a proportional relationship between temperature and pressure
  • Temp up = Pressure up
• Gas Molecules and Volume

  • Decreasing the volume of a container leads to an increase in pessure
  • Volume of the container is reduced = compressed
  • Volume of the container is increased = expanded
