About O/L Science: O/L Science integrates physics, chemistry, and biology into a single subject across Grade 10 and 11.

• Conduction: heat transfer through solids by particle vibration/free electrons
• Convection: heat transfer in fluids by bulk movement of heated fluid
• Radiation: heat transfer by infrared EM waves; no medium required
• Specific heat capacity (c): energy to raise 1 kg by 1 °C; Q = mcΔT
• Latent heat: energy absorbed/released during state change at constant temperature

Must know

• Convection: bulk fluid movement; hot rises, cool sinks
• Radiation: infrared EM waves; no medium needed; black bodies emit/absorb best
• Q = mcΔT (heat = mass × specific heat capacity × temperature change)
• Water: c = 4200 J/kg°C (high — resists temperature change)
• Latent heat: energy for state change at constant temperature
