Question

Solutes lower the freezing point of water by _____.
helping water molecules to form crystals

making it harder for water to form crystals

stopping water molecules from moving

making the water molecules move faster

Answer 1

Solutes lower the freezing point of water by **making it harder for water to form crystals**. When a solute is added to water, it disrupts the hydrogen bonding between water molecules, which hinders the formation of the organized crystal structure necessary for ice.
