In a demonstration of heating by convection, your teacher heats a beaker of water to boiling on a hot plate. Which hypothesis correctly describes how heating by convection occurs? (AKS 7d)
a- As particles of a substance are heated, energy is transferred to neighboring particles by collisions of the particles.
b - As particles of a substance are heated, energy is transferred by gas bubbles within a liquid.
c - As particles of a substance are heated, energy is transferred due to the radiant energy from the heat source.
d - As particles of a substance are heated, energy is transferred as more energetic particles within the substance rise and less energetic particles sink.
