Key Topics to Revise

1

Modes of Heat Transfer

  • Heat always flows from a hotter body to a colder body until thermal equilibrium is reached.
  • Conduction occurs in solids where particles vibrate and transfer energy without moving from their positions.
  • Convection happens in fluids (liquids and gases) where heated particles move upward, carrying heat with them.
2

Radiation and Black Body Radiation

  • All objects emit radiant energy in the form of electromagnetic waves, mainly in infrared region.
  • A perfect black body absorbs all incident radiation and emits radiation depending only on its temperature.
  • Wien’s displacement law states that as temperature increases, the peak wavelength of emitted radiation decreases.
3

Greenhouse Effect and Newton's Law of Cooling

  • Solar constant is the amount of solar energy received per square meter per second at Earth’s atmosphere: 1360 W/m².
  • Greenhouse effect keeps Earth warm by trapping infrared radiation via CO₂ and other gases.
  • Increased CO₂ from fossil fuels enhances greenhouse effect, leading to global warming.
