ASTRONOMY 3: Introductory Astronomy: The Solar System

Winter 2012

Lecture 4 Properties of matter


Potential and kinetic energy

different forms of potential energy: mechnical, electrical, chemical, atomic

different forms of kinetic energy: waves, heat, sound, radiation

Force: Rate of change of energy

Temperature, density, and pressure = force/unit area

Pressure = density times temperature

phases of matter: solid, liquid, gas, plasma

multi phase equilibrium

temperature and heat (flow of energy)

heat and phase transition

heat transfer processes: conduction, convection, radiation

mass transfer process: diffusion, differentiation, and advection

Microscopic world

atoms and elements

mass and energy (E=C^2)

hydrogen atoms:

energy level: ground state, excited states, ionized state

Line radiation

Forces of Nature
