Compare heat-transfer processes, then move to heating/cooling curves to interpret specific heat, latent heat, and state change.

  • SEC G3 Physics 2027
Learning goals
  • Explain heating from higher to lower temperature until thermal equilibrium
  • Describe conduction in solids through particle vibration and mobile electrons
  • Describe convection in fluids through density changes and bulk motion
  • Explain that energy transfer by electromagnetic radiation needs no material medium
  • Explain how surface colour, texture, temperature and area affect radiation transfer rate

      Study lensDistinguish conduction, convection, and radiation by the energy-transfer path.11 min activity

      Try this

      Switch view when stuck: if the process feels abstract, use the graph; if the graph feels abstract, trace the energy path.

      Learn to

      • Distinguish conduction, convection, and radiation by the energy-transfer path.
      • Connect specific heat capacity and latent heat to the shape of heating or cooling curves.
      • Interpret why temperature can stay constant while energy is still transferred during a state change.

      Governing idea

      Heating without change of state uses Q = mcΔT; a phase change uses Q = mL. Transfer rate depends on temperature difference and the transfer mechanism.

      Model boundary

      Objects are treated as having uniform temperature with constant material properties. Unshown heat capacity and environmental losses are simplified.

      Avoid this trap

      Temperature measures thermal state, not the total internal energy stored. A larger cool object can contain more internal energy than a smaller hot one.

      How to explore

      Switch between transfer processes and heating curves so temperature change and state change stop feeling separate.

      Predict the outcome, change one variable at a time, then interpret the result. Completion records participation only and does not award mastery.
