Topic list
Topic 1
Heat is a form of energy, while temperature tells how hot or cold a body is. Heat is measured in joule or calorie; temperature in degree Celsius, degree Fahrenheit, or kelvin.
Topic 2
Heating can raise temperature, expand substances, and change state. Cooling can reverse many of these changes.
Topic 3
Heat is transferred by conduction, convection, and radiation.
Topic 4
A thermos flask reduces heat transfer by conduction, convection, and radiation to keep liquids hot or cold for longer.
