• Three mechanism of heat transfer

  Conduction, Convection, and Radiation
• Transferred due to the contact from a hot body to a cooler body

  Conduction
• Heat is transferred by 1 one molecule to another molecule

  Conduction
• Give 2 examples of Conduction

  walking barefoot at a hot sand and touching a hot pot
• Allows heat to pass through easily

  Conductors
• Example of conductors

  Aluminum, Gold, and Copper
• materials that prevent heat to pass through

  Insulators
• Examples of Insulators

  Plastic and wood
• Parts of a calorimeter

  Insulating cover, Holes, Inner vessel, outer vessel, and stirrer
• Example of use a thermal insulation

  Picnic coolers, it prevents heat from the outside to enter
• Some materials for thermal insulation for houses

  Fiberglass and Cellulose
• Travel by air or empty space

  Radiation
• Examples of radiation


  Heat from the sun and camping
• Ideal absorber


  Black body
• black color


  absorbs heat
• silver or light colors


  reflect the light or heat
• states that the current and voltage in a resistor are related by the resistance of the resistor

  Ohm's Law
• Ohm's Law formula

  V=IR
• The same current flows both resistors while the voltage from the battery is split

  Series
• The voltage across each resistor is equal to the voltage of the battery while the total current is plit

  Parallel
• In LRC circuit to achieved LC the resistance must be

  0
• Voltage source: Magnetic field

  Inductor
• Voltage source:electric field

  Capacitor
• Circuit is connected to sinusoidal voltage, at some point or at a particular frequency when it matches the frequency of the oscillating energy

  Resonance
• LRC: Input source increase

  across the capacitor decreases and across the inductor increases
• High pass filter

  Across the inductor
• Low pass filter

  Across the capacitor
• the change in direction from one medium to another medium obliquely

  Refraction
• when is the angle of incidence greater

  less dense to denser medium
• when is the angle of refraction greater

  denser medium to less dense
