Atomic Structure, Temperature, and Pressure

Temperature and Pressure

• Decrease in temperature leads to a decrease in pressure.
• Partial pressure also decreases.

Gases

• When volume decreases, pressure increases.
• Gases love energy.

Movement of Particles

• Particles move down a concentration gradient, from high to low concentration.
• Increased temperature accelerates the rate of movement/diffusion.

Atomic Structure

• Shells: Electron shells.
• Subatomic particles:
  • Protons (p)
    • Charge: Positive (+ue)
    • Mass: Significant
  • Neutrons (n)
    • Charge: Neutral
    • Mass: Significant
  • Electrons (e-)
    • Charge: Negative (-ve)
    • Mass: Negligible

Atoms

• Atoms are the smallest building blocks of matter.
• Structure of atoms involves the arrangement of these subatomic particles.
