How heat moves
Heat is thermal energy that flows from warmer to cooler objects. It transfers by conduction (particle collisions in solids), convection (movement of fluids due to density differences), and radiation (electromagnetic waves through matter or vacuum).
Adding heat increases the average kinetic energy of particles, so particles move faster and farther apart; removing heat slows motion. In fluids, warmer, less dense regions rise while cooler, denser regions sink—creating convection currents.

Q5
Label the convection cell: drag the correct label to each side.
Left side near heat source is rising fluid. Right side is sinking fluid.
Warmer, less dense (rises)
