  1. 1. Heat flows from a body at higher temperature to one at:
    • (a) the same temperature
    • (b) higher temperature
    • (c) lower temperature
    • (d) no temperature

    • (b) radiation
    • (c) reflection
    • (d) conduction
  3. 3. Heat from the Sun reaches Earth by:
    • (a) radiation
    • (b) conduction
    • (c) convection
    • (d) boiling
  4. 4. Heat transfer in liquids and gases by movement is:
    • (a) conduction
    • (b) convection
    • (c) radiation
    • (d) insulation
  5. 5. What is the difference between heat and temperature?
  6. 6. Name the three modes of heat transfer.
  7. 7. Explain conduction, convection and radiation with an example of each.

  1. 1. (c) lower temperature — Heat flows from hotter to colder.
  2. 2. (d) conduction — Through solids it is conduction.
  3. 3. (a) radiation — It travels through space by radiation.
  4. 4. (b) convection — It is convection.
  5. 5. Heat is energy that flows; temperature measures how hot or cold something is.
  6. 6. Conduction, convection and radiation.
  7. 7. Heat is transferred in three ways. Conduction is the flow of heat through a solid from its hotter part to its cooler part, without the material moving — for example, the handle of a metal spoon becomes warm when the other end is in hot tea. Convection is the transfer of heat in liquids and gases by the actual movement of the heated material: heated fluid becomes lighter and rises while cooler fluid sinks, as when water heats in a pan. Radiation is the transfer of heat without any material in between, which is how the Sun's heat reaches the Earth across empty space. Together, these three modes explain almost all the heating we observe in nature.
