6
Q

Water particles near the heat get more [ ], so they start moving around [ ]. The distance between the particles [ ], and it becomes [ ] dense. The hotter water [ ] above the denser, cooler water. As the hot water rises it displaces the cold water, making it sink to the heat source, it then heats up and rises

A
energy
faster
