Which row correctly describes the spacing and motion of the molecules in water and in ice when both are at a temperature of 0 °C? [Table with spacing and motion descriptions]
Amolecules in ice are further apart than molecules in water, molecules in both ice and water have the same average speed
Bmolecules in ice are further apart than molecules in water, molecules in ice travel more slowly than those in water
Cmolecules in ice are closer than molecules in water, molecules in ice travel more slowly than those in water
Dmolecules in ice are closer than molecules in water, molecules in both ice and water have the same average speed
✓ Correct answer
A: molecules in ice are further apart than molecules in water, molecules in both ice and water have the same average speed
