1). Could be true or false, depending on what the missing word is.
2). The molecules IN frozen water are in motion.
3). Ice has plenty of thermal energy. Everything that's at any temperature above -273°C has some.
4). It'll flow both ways, but vastly more FROM the water TO the ice.
All matter contains thermal energy, including ice, which has moving molecules. When ice is combined with water, heat flows from the warmer water to the colder ice. These principles are fundamental in understanding thermal energy and heat transfer.
