Question

Match the key word(s) to the correct form of Energy Transfer.

1) Conduction
2) Convection
3) Radiation
A. currents
B. electromagnetic waves
C. touching or contact

Answer 1

Conduction is heat transfer through physical contact, convection is heat transfer by the movement of fluids, and radiation is heat transfer through electromagnetic waves.

Step-by-step explanation:

In the context of energy transfer, conduction refers to heat transfer through direct physical contact between two objects. Examples include heat transferred from a stove to a pan, or from a metal spoon to hot coffee.

On the other hand, convection involves heat transfer by the movement of fluids at different temperatures and densities. A common example is warm air rising from a fireplace.

Radiation, the third form of energy transfer, occurs when heat is transferred through electromagnetic waves. One example is the warming of the Earth by sunlight.
