Which row correctly describes the ordering and motion of the molecules in liquid water and in ice when both are at a temperature of 0 °C?
Aordering: a regular pattern of molecules in ice but not in water, motion: molecules in both ice and water have the same average speed
Bordering: a regular pattern of molecules in ice but not in water, motion: molecules in ice travel more slowly than those in water
Cordering: a regular pattern of molecules in both ice and water, motion: molecules in ice travel more slowly than those in water
Dordering: a regular pattern of molecules in both ice and water, motion: molecules in both ice and water have the same average speed
✓ Correct answer
A: ordering: a regular pattern of molecules in ice but not in water, motion: molecules in both ice and water have the same average speed
