Sort real-world examples into the correct heat transfer category.
Identify which examples could involve more than one heat transfer method.

Warm Up

Match each term to its definition

Draw a line connecting each term on the left to its correct definition on the right. Or write the matching letter next to each term.

Term	Your answer	Definition
Conduction		A. Energy cannot be created or destroyed, only transferred or transformed.
Convection		B. Heat transfer through electromagnetic waves, requiring no medium.
Radiation		C. A change in the form of energy, e.g. chemical to thermal.
Specific heat capacity		D. Heat transfer through a fluid (liquid or gas) as particles move in currents.
Thermal expansion		E. The increase in size of a material when its temperature increases.
Law of conservation of energy		F. Heat transfer through direct contact between particles in a solid.
Energy transformation		G. Energy moving from one object or place to another without changing form.
Energy transfer		H. The energy needed to raise 1 kg of a substance by 1 °C.

Your Turn

Sort it!

Write each example into the correct column. Then circle any THREE examples that could involve more than one heat transfer method.
