- 02Convert between Celsius and Kelvin and explain absolute zero
- 03Describe conduction, convection and radiation
This is the trap that catches almost everyone. Temperature measures how hot something is — really, the average kinetic energy of its particles. Heat is energy in transit, flowing from a hotter object to a cooler one. A sparkler burns at 1500 °C but carries almost no heat (tiny mass); a warm bath is only 40 °C yet holds enormous energy. High temperature does not mean lots of heat.
