Three Methods

Q1.What is conduction?

Answer

Heat transfer through direct contact. Molecules vibrate and pass energy to neighbors (like a metal spoon getting hot in soup).

Q2.What is convection?

Answer

Heat transfer through the movement of fluids (liquids or gases). Warm fluid rises, cool fluid sinks, creating a current.

Q3.What is radiation?

Answer

Heat transfer through electromagnetic waves (no medium needed). The Sun heats Earth through radiation across empty space.
