Answer:
The temperature of a substance increases, then the substance's particles move faster and apart because of kinetic energy. As space between increases, the substance expands, which causes an increase in volume.

Answer:
Thermal expansion changes the space between particles of a substance, which changes the volume of the substance while negligibly changing its mass (the negligible amount comes from energy-mass equivalence), thus changing its density, which has an effect on any buoyant forces acting on it.
